Nice job Krista! I think some hens just need more calcium than others. I have 12 laying hens that all get the same feed and live together. There is just one that has laying problems. I don't think she eats the oyster shells that are in the coop. She's been getting ground up calcium in scrambled eggs once a week and is back to laying normally again. Not sure if it is her age, or just that she isn't eating as well as the other birds.
