One of my BJG hens has a large soft abdomen. She is acting fine but I noticed that she just looks different. First I noticed her backside is large and hangs low. It is mostly bare with new feathers emerging. My first though was egg bound. I held her and she is very heavy and I think I can feel a few eggs in there. She is eating, walking around, roosting and acting normal from what I can tell. What to do first?
