This whole business started about a month or so ago when I posted about my ameracuana hen laying an egg covered in a membrane like sac. She has layed some normal eggs inbetween and some soft shelled eggs. The layer crumbles that I feed my girls has calcium in it, and since this started happening I added lots and lots of oyster shell to the run. Now.. all 3 of my girls are laying soft shelled eggs! Either that or poor Mae, my ameracauna is laying more than one soft shelled egg in a day. Another thing that Mae has started doing is laying eggs in odd places, such as in the run, or under her roost. Are they not absorbing the calcium from the oyster shell? Is there something else that I can supplement calcium with? This is just awful, I feel terrible that this problem is not improving! Does anyone have any idea what could be causing this problem?
