Hi everyone. I have a hen that is a little over a year old. She recently has been having some troubles with laying eggs that have thin shells/no shells. They have oyster shell available in the coop and run. They free range about 2-5 hours a day. I feed them New Country Organics grower and I ferment it. I also feed barley fodder. Since her problem started, I also give them layer pellets. But, she still is having a problem with her shells. I have powdered calcium carbonate. When I am able to get her to eat it, it helps. She is a very picky eater and it has been difficult. Today I tried little pieces of raw chicken wing tips. They were cut up into little pieces and she loved them. I don't like the idea of feeding chicken to my chicken, but I don't want her laying shell-less eggs. Anyone have any idea how much wing bone I should feed her? I was thinking I would feed a little every 2-3 days, but don't know how much. Thanks for any suggestions!
