I have a 3 yr old rhode island red mix hen. Her belly is puffy like a water balloon. It isn't hard but squishy, I can't feel any eggs. It looks like she either has a ruptured bowel or she is an internal layer. I have her isolated for the rest of the flock as they pecked a spot open on her back. Her back is healing really well, is there anything I can do for her other symptoms? Pip is not from a hatchery. They used to be free ranged, but now are in a very large enclosure. Could that have anything to do with it? HELP!!!!!
