Chicken Oyster Shell Feeder and Grit Feeder Combo - Calcium & Grit

In this review of the Chicken Oyster Shell Feeder and Grit Feeder Combo the bottom line is simple: this is a practical, no-nonsense supplement station for small flocks that gives hens access to both calcium and grit without forcing supplementation. The reviewer found it particularly useful for backyard keepers who want a tidy, mounted option that automatically refills the eating cup and keeps oyster shells and grit dry and accessible. It is best for owners who want a low-maintenance way to support eggshell strength and digestion.

Key Features

• Separate calcium access: Allows hens to take oyster shell as needed so layers get extra calcium only when they require it, which helps shell hardness and durability.
• Grit for digestion: Provides grit to help chickens grind food and extract nutrients, especially useful for birds that do not free range.
• Auto-refill cup: The feeder refills the eating cup automatically, cutting down on frequent refills and saving time for the keeper.
• Easy mounting: The back of the feeder slips onto the head of a screw so it installs quickly on any wood surface in a coop or run.
• Drainage design: Drainage holes let water escape while keeping oyster shells and grit in place, reducing mess and spoilage.
• 3 lb capacity: Each feeder holds up to 3 lbs so a small flock can access supplements without constant attention.

Who It's For

The feeder combo is ideal for backyard poultry keepers with small flocks who want to improve eggshell quality and help birds digest feed without changing their feed mix; it works well for people who keep layers, mixed flocks with roosters, or birds that rarely free range. The design suits owners who prefer a mounted, tidy solution that is easy to refill and clean.

Those with very large flocks or commercial operations should look for larger-capacity industrial equipment, and keepers who need weatherproof, heavy-duty metal dispensers for exposed outdoor use may prefer a different style. This product shines for household coops and moderate climates.
