Oyta Hen Oyster Shell is a great food supplement for all hens, poultry, and waterfowl.
Oyster shell grit is a valuable source of calcium, which birds require for egg shell production, as well as healthy bones. This makes it especially valuable to laying birds.
Hen Oyster Shell is soluble and so is digested by the birds, providing improved digestion and a slow calcium release.
Hen Oyster Shell is 4-7mm in size.
