My sister has a few hens that i gave her and one has laid a soft-shelled egg almost every day for almost 2 weeks. The weird thing is that they roost on the top of her small store bought coop and every morning there is a softshelled egg sitting there. so she is laying it at night, and after roosting up. I get about one soft-shelled egg for every hundred or so. And rarely get them back to back. What can she do? I told her we might have to cull her. Has anyone seen this and can they grow out of it? one of the eggs even had a tail that didn't seal off. I will put a pic below.
