Hi, I just found one of my three year old bantam buff orpington hens in the coop tonight, not on a perch, who has a seriously bloated abdomen, almost like an inflated balloon. I can't feel any hardness like an egg, but it is so bloated and stretched it is hard to tell. I don't see any blockage for her poops, although she has a bit of very dry poop stuck to a couple of feathers, but had to look for it. I just lost a hen recently to my first case of sour crop (don't know the cause of the sour crop), if that is relevant. This one's crop feels normal thank god, but the bloat seems serious. It is bulging past and around the rib cage. Any ideas? I don't even know what this could be.
