Oyster Shell Calcium

Oyster shell calcium for laying hens supplies a slow-release calcium source that supports normal eggshell formation. Offer it separately in a clean, dry feeder so actively laying hens can consume it according to need. It complements a balanced layer ration and does not replace insoluble grit.
