To clarify the nutrition side, this comparison puts the Chicken Oyster Shell Feeder and Grit Feeder Combo head to head against the CluckRoots Chicken Grit and Oyster Shell Feeder so you can see which supplement system matches your coop in 2026.
Before buying, check your local ordinance or zoning rules for keeping backyard chickens, and choose a coop sized to predator-proof your flock.
Both feeders give hens free choice access to calcium and grit, but they approach the job very differently in terms of build, capacity and daily convenience.

Pros
- Automatic gravity refill keeps trays filled without constant attention
- Easy installation that mounts securely and frees up floor space
- Drainage holes prevent water buildup while retaining shell and grit
- Sturdy plastic build with lids to keep contents clean and dry
Cons
- Plastic construction is less rugged than metal in extreme weather or with aggressive peckers
- 3-pound capacity may require frequent refills for larger flocks
- Mounting system requires a wood surface and screw, not ideal for all-wire coops without modification
The Revolutionary Chicken Oyster Shell and Grit Feeder Combo is a 2-pack gravity feeding system designed for backyard laying hens. It provides separate, free-choice access to calcium and grit, so hens can supplement as needed while roosters are not forced to consume extra calcium. It is perfect for small to medium backyard flocks, especially those that do not free range.
Standout features include automatic refill and excellent real-world convenience. Each 3-pound hopper dispenses into a small eating cup as chickens peck, so you refill less often. Reviewers consistently praise how quickly chickens take to the feeders and how easy they are to fill, mount, and keep clean during daily coop care.
Design and build quality are simple, practical, and flock friendly. The white plastic feeders measure 4.5 x 4.5 x 10.5 inches, include protective lids, and mount by slipping onto a screw head on any wood surface. Drainage holes in the tray let rainwater escape while keeping oyster shell and grit inside, and the wall-mounted design saves valuable floor space.
There are a few minor drawbacks to consider. The plastic material, while sturdy for most coops, is not as heavy duty as galvanized metal over many years outdoors. The 3-pound capacity is generous for small flocks but larger flocks will need more frequent refills, and installation is limited to wood surfaces without added hardware.
Overall, this combo offers outstanding value and functionality for backyard chicken keepers. It is well made, easy to install, and solves the common problem of messy, wasteful supplement bowls. For anyone wanting cleaner supplementation and stronger eggshell support with minimal effort, this is an excellent buy.

Capacity: 3 pounds per feeder, Dimensions: 4.5 inches L x 4.5 inches W x 10.5 inches H
Material: Durable Plastic, Color: White, Power Source: Manual gravity fed
Included: 2 feeders with trays and lids, Mounting: Slip-on screw mount for wood surfaces
Special Features: Automatic Refill, Easy Installation, Drainage System to keep contents dry
Pros
- Anti-waste design significantly reduces spillage compared to open bowls
- Weather resistant construction with rain cover and drainage keeps supplements dry
- Clear viewing window makes daily monitoring fast and convenient
- Lift-off hanging system allows easy removal for cleaning without tools
- Durable galvanized steel withstands pecking and outdoor exposure
Cons
- 3-pound capacity may require frequent refills for flocks larger than 8 birds
- Requires wall, fence or coop mounting, not suitable as a freestanding feeder
- Limited real-world feedback available to verify long-term durability claims
The CluckRoots Chicken Grit and Oyster Shell Feeder Combo is a dual-compartment wall-mounted feeder designed to dispense grit and oyster shell separately for small backyard flocks. It is ideal for busy keepers with 3 to 8 hens, as well as owners of quail, ducks, turkeys and other game birds who want a tidy, efficient supplement station.
In real-world use, the controlled-flow ports are the standout feature, dispensing just enough supplement while preventing chickens from kicking or billing it out. The clear front window lets you monitor levels at a glance, and the 3-pound capacity means most small flocks can go up to two weeks between refills, saving time and reducing waste.
Build quality is a strong point, with heavy-duty galvanized steel, a matte finish and a sloped rain lid that shields contents from debris and droppings. The bottom drainage outlet helps water escape quickly after rain, keeping grit and shells dry and usable, while the metal construction resists pecking damage and outdoor corrosion.
There are a few limitations to consider. The compact 4 by 4 inch footprint and 3-pound capacity are not ideal for larger flocks, and the feeder must be mounted to a wall or fence, so it is not freestanding. As a newer product, long-term durability is based on materials and design rather than extensive user history.
Overall, this is a smart, well-built upgrade over open bowls for keepers who want less mess and lower supplement costs. If you have a small to mid-size flock and want a clean, weatherproof and low-maintenance feeding solution, this combo feeder is a practical and stylish choice for your coop.

The ULENDIS 2 Pack Chicken Oyster Shell and Grit Feeder is a specialized supplemental feeder for backyard poultry keepers. It is designed to dispense oyster shell for calcium and grit for digestion separately from main feed, making it perfect for chickens, ducks, pigeons and other small birds.
In real world use, the gravity-fed system works reliably to keep the trough filled without daily attention. Each feeder holds enough for up to 6 chickens for more than 12 days, which saves time and keeps supplements consistently available to support stronger eggshells and healthy digestion.
Build quality is a clear highlight thanks to the heavy-duty metal construction. It withstands constant pecking and outdoor exposure, while the movable lid blocks rain and built-in drain holes prevent moisture buildup. Smooth, arc-shaped edges also make feeding more comfortable and safe.
There are a few limitations to consider. These are compact supplement dispensers at 3.9 by 3.9 by 10 inches, so they are not a replacement for a large capacity main feeder. You will also need a fence, wire mesh or wall for installation, as they cannot stand alone.
Overall, this is a smart, durable and well thought out accessory for small to medium backyard flocks. If you want a clean, weatherproof and low maintenance way to offer oyster shell and grit, this 2 pack delivers excellent value and functionality.
Product Dimensions: 10.7 x 6.3 x 4.6 inches for the 2 pack, individual feeder size is 3.9 inches L x 3.9 inches W x 10 inches H. Item Weight: 2.79 pounds total. Model Number: US-DBL20250701-011.

- Sturdy rust resistant metal build suitable for indoor and outdoor coops and farms
- Versatile installation with both screw and hook mounting options
- Easy to refill through top lid and requires no assembly
- Gravity flow design delivers steady access without waste
Cons
- Weld quality on wire hangers can be inconsistent, screw mounting is more reliable
- Low front lip may allow minor spills during feeding
- Capacity may feel modest for larger flocks needing more frequent refills
The Leinuosen 2-pack feeder set includes dedicated dispensers for oyster shell and grit, designed for backyard chicken and duck keepers who supplement their flock's diet. It is perfect for small to medium coops where clean, separate access to calcium and digestion aids is essential.
In real world use, the gravity fed design keeps supplements flowing into the lower tray while the dual lids keep contents dry and free from dirt, droppings and insects. Owners report that shells stay fresh for over a week even in rainy conditions, and hens adapt to the feeders quickly without waste.
Built from welded metal with a rust resistant finish, these feeders handle indoor and outdoor conditions without bending or fading. The one piece construction requires no assembly, and the red and black chick pattern makes it easy to tell the grit and oyster shell feeders apart.
The main drawbacks noted are inconsistent welds on the wire hangers, which makes screw mounting the more reliable option, and a relatively low front edge that can allow some spillage. The 10.24 inch size is efficient for small flocks but may require more frequent refills for larger ones.
Overall, this is a durable, weatherproof and space saving solution that keeps supplements clean and accessible with minimal maintenance. It is a strong choice for poultry owners who want tidy, wall mounted feeders that reduce daily chores and protect feed quality.

The ETSSXYSO 2-Pack Chicken Grit and Oyster Shell Feeder is a gravity fed supplement station designed for backyard poultry keepers. It is ideal for owners of chickens, ducks, quail and other small flocks who need a clean, dedicated way to offer grit and oyster shell separately from main feed.
Standout features include the upgraded clear visual window and high capacity 5 pound hopper. The window lets you monitor levels in seconds, while the gravity flow keeps feed available without spills. In real world use, this means fewer refills and less waste on the coop floor.
Build quality is a major strength thanks to the heavy duty metal construction. The feeder is weatherproof and rust resistant, so it holds up well to sun, rain and humidity inside or outside the coop. The hanging mount design keeps the tray elevated and cleaner than ground feeders.
There are a few tradeoffs to consider. The 5 pound size is perfect for small to medium flocks but will need more frequent attention for larger flocks. It is also specifically sized for supplements like grit and shell, so it is not a replacement for a large capacity pellet feeder.
Overall, this combo offers excellent value and practicality for most backyard setups. With durable materials, thoughtful design and easy installation, it is a reliable choice for keepers who want stronger eggshells, healthier digestion and a tidier coop.

Head-to-Head: Which Feeder Handles Real Coop Life Better?
Build Quality and Weather Protection
The Chicken Oyster Shell Feeder and Grit Feeder Combo uses a compact gravity fed design with drainage holes in the cup that let rainwater escape while keeping oyster shell and grit inside. It is made to slip onto a screw head mounted to any wood surface in your coop or run, which keeps installation simple and keeps the feeding area off the floor.
The CluckRoots Chicken Grit and Oyster Shell Feeder takes a more heavy duty approach with galvanized steel construction, a sloped rain cover and a dedicated drainage outlet at the bottom. That enclosed housing is designed to shield supplements from droppings, windblown debris and heavy rain, and owners who keep feeders on exposed fencing often report it stays drier and cleaner.
If your coop is covered and you prioritize a light, low profile feeder, the Revolutionary Chicken option feels perfectly adequate and easy to keep clean. If your run is open to the elements or you want a more permanent, weather resistant fixture, the steel build and rain cover of the CluckRoots model gives you extra peace of mind, especially if you are also planning a Large Metal Chicken Run 10X20 Walk In 10X20 setup.
Capacity and Waste Control
The Chicken Oyster Shell Feeder and Grit Feeder Combo automatically refills its small eating cup as hens peck, which prevents the scattering you get with open bowls and helps roosters avoid extra calcium they do not need. It is designed for steady free choice access rather than bulk storage, so you will check and refill it more often than a large hopper.
The CluckRoots Chicken Grit and Oyster Shell Feeder is built around an anti waste dispensing design that the brand says can reduce supplement waste by up to 40 percent compared to open dishes. It holds roughly a two week supply for a small flock of 3 to 8 hens, so busy keepers can go longer between refills without worrying about hens running out of grit or calcium.
For a tiny backyard flock where you enjoy daily interaction, the smaller, cup style feeder offers precise portioning and less stale product sitting in the hopper. For larger small flocks or for keepers who travel or work long hours, the higher capacity and controlled flow of the CluckRoots feeder means fewer chores and lower annual supplement costs.
Installation and Everyday Ease
The Chicken Oyster Shell Feeder and Grit Feeder Combo installs with a single screw per feeder, no assembly required, and the whole unit lifts off the screw head for quick cleaning or refilling. Its minimal footprint is ideal if you want to mount separate oyster shell and grit stations side by side without crowding your coop wall.
The CluckRoots Chicken Grit and Oyster Shell Feeder also arrives ready to use with zero assembly and includes both heavy duty screws and versatile hooks so you can mount to wood, wire mesh or fencing. Its lift off design is equally convenient, you simply lift the feeder off its mounts to clean or refill, with no tools needed.
Both are beginner friendly, but the choice comes down to wall space and permanence. Choose the Revolutionary Chicken combo if you want the lightest, most discreet mount on a wooden coop interior. Choose the CluckRoots feeder if you prefer a sturdier, more anchored feel on a run panel or exterior wall where extra stability matters.
Monitoring, Versatility and Coop Fit
The Chicken Oyster Shell Feeder and Grit Feeder Combo keeps monitoring simple, you can see the level in the cup at a glance and peek into the reservoir to judge when to refill. It is described as helpful for hens that do not free range and for mixed flocks where only laying hens need extra calcium.
The CluckRoots Chicken Grit and Oyster Shell Feeder adds a clear front facing window so you can check supplement levels without opening the lid at all. The brand also positions it as universally applicable for pigeons, doves, turkeys, ducks, geese, quail, pheasants and other game birds, which is useful if you keep more than just chickens.
Visually, the Revolutionary Chicken feeders are utilitarian and blend into a functional coop, while the CluckRoots model is styled with clean lines to complement a backyard coop aesthetic. If you value quick visual checks during morning chores or you manage multiple poultry species, the window and broader bird compatibility of the CluckRoots feeder stand out.
Footprint and Long Term Value
The Chicken Oyster Shell Feeder and Grit Feeder Combo has a compact, lightweight footprint that frees up floor space and keeps the feeding area tidy, especially in smaller coops. Its automatic refill cup means less spilled supplement on the ground and less frequent sweeping.
The CluckRoots Chicken Grit and Oyster Shell Feeder occupies a bit more wall space due to its steel hopper and rain cover, but that size translates into longer intervals between refills and a more robust presence that withstands pecking and weather. For keepers who want to set and forget for a week or two, that trade off is often worth it.
Another option worth a look is the 2 Pack Chicken Oyster Shell Feeder and Grit, which offers a similar gravity fed metal design with a visualization window and two pack value if you want dedicated bins for shell and grit at a more budget conscious entry point.
Which One Should You Get?
Choose the Chicken Oyster Shell Feeder and Grit Feeder Combo if you keep a small flock in a covered coop, want the simplest install, and prefer compact, separate stations for oyster shell and grit that you can check daily. It is the more streamlined, low profile pick for keepers who value simplicity, easy cleaning and giving hens true free choice calcium without overcomplicating the setup. It pairs well with a tidy coop routine like the one described in Small Pet Select Hemp HURD Chicken Coop Bedding vs RentACoop Premium Hemp Bedding.
Choose the CluckRoots Chicken Grit and Oyster Shell Feeder if you want maximum waste reduction, longer refill intervals and all weather durability in a single, stylish unit. It is the better fit for busy keepers, exposed runs, or mixed poultry flocks where the clear viewing window, larger capacity and galvanized steel housing will save you time and keep supplements dry. If you are also debating seasonal gear, this comparison of automatic port chicken feeder and cup waterer set vs chicken coop heater can help you prioritize what your flock needs next.
Who Should Skip Both?
These gravity wall feeders are not ideal for keepers who need a fully predator proof locking solution or a complete feed system for pellets and crumbles rather than supplements alone. If your main concern is nighttime security, an automatic door or a dedicated Chicken Coop Lock Predator Proof is not the right choice to replace with a grit feeder, and if you raise chicks that need starter feed or you want a large capacity primary feeder, skip this category and look for a full size hanging or treadle feeder instead.
Frequently Asked Questions
Do hens really need separate oyster shell and grit feeders?
Yes, offering oyster shell and grit free choice lets each bird take what it needs. Laying hens will consume more calcium for harder shells while roosters and non laying birds can avoid it, and grit helps all birds grind and digest food, especially if they do not free range.
Which feeder wastes less oyster shell and grit?
Both reduce waste compared to open bowls, but the CluckRoots Chicken Grit and Oyster Shell Feeder is specifically designed with an anti waste dispensing system that limits how much supplement sits in the tray. The Chicken Oyster Shell Feeder and Grit Feeder Combo also limits waste with its small auto refill cup, though its smaller reservoir means more frequent refills.
Can I mount these feeders outside in the run?
You can, but weather protection matters. The Chicken Oyster Shell Feeder and Grit Feeder Combo relies on drainage holes and works best under cover, while the CluckRoots Chicken Grit and Oyster Shell Feeder adds a sloped rain cover and drainage outlet to keep supplements dry in exposed locations.
