I have them on a mixed flock feed and provide oyster shells that I never see them use. Today I noticed that one of my hens was eating an egg so I'm wondering if they're not getting the right nutrition. I want to know if I should use meatbird crumbles and if I'd need to supplement the calcium still. I just need something that'll be good for everyone to eat. I have two ducks (both drakes), two turkey poults that I'm keeping as pets and eight chickens one of which is a rooster.
