I have an 18mo old BO who hasn't laid an egg in months. She sits on the nest a few times a week and gets off singing, but doesn't lay. She eats well, hangs with my roo all day in the yard and doesn't appear to be in any distress. I decided to feel her abdomen tonight just to see if it was normal. It is distended and feels fluid-filled. She's a big girl anyway, but her abdomen feels like a softball sized water balloon. I felt my other hens to be sure and they didn't feel at all like that. Is she egg bound? Is it possible to be egg bound for 4 months and still walking around? What should I do for her? Any help is most appreciated. Edit: I've been doing some more research and it's looking like it could be sterile peritonitis. Is there anything I can do to make her recover, or do I just need to cull her?
