Hi all, I recently saw a post in a thread (don't remember which one though) that mentioned some foods that can interfere with calcium absorbtion. Can anyone tell me what foods those are? What is the component that causes the interference? And at what amount per hen do you start having problems? I am asking because I am dealing with a hen who has dropped several shell-less/membraneless eggs from the roost at night over the last couple weeks and I am trying to determine if this is calcium deficiency, internal laying, or what. My girls get soy-free organic layer pellets (from Rainbow Egg Farm), oyster shell, and water (which I only recently learned to add ACV to) all day every day. They also get kitchen scraps in the evenings, but only things that are on the treat list. I don't have a knowledgable avian vet locally and I have only been keeping hens for 3 months now so I am really hoping for some knowledge and advice from here. Thanks!
