I know this is an old post, but I've been searching the Internet for information on hens being egg bound for long periods of time. My hen, Lorraine, is an ex commercial hen and when we got her about 2 months ago, I thought her abdomen looked distended but I wasn't sure and she seemed happy enough. In those first few weeks she seemed very well but didn't lay. I eventually convinced myself that her abdo wasn't normal and took her to the vets. They scanned her and found an egg. They have calcium which started her muscle contractions, I gave her a warm bath, but the egg was so low down in the abdo, she couldn't pass it. The following day she was back to her usual happy self and has been the same since then. This was a couple of weeks ago. We drained some fluid from her abdomen, the vet thinks she has a sterile peritonitis. Her prognosis is guarded but I'm keen to hear from anyone else who's been may have been through similar? She seems so happy despite this egg being such inside her!!
