One of our lovely brahma chicks, 10 days old, appears to be constipated. Her vent is slightly distended and pulsing. It started last night. I noticed she was standing still, wings hanging low, and her vent red and pulsing, as if she were pushing. She also appeared to have some dried poo below her vent, so I treated it as if it were pasty butt: cleaned off the dried poo with a warm wet paper towel and olive oil. That improved her, but then this afternoon it started again. She seems to be straining to push out a poo, is hanging her wings down, and keeping her butt in the air as she dozes off. A little while ago, I did the same treatment as last night, and it seemed to improve her, but now she is straining again, and just started doing a distress cheep. Any ideas???? Could she have something stuck in there, like an undigested pine chip?
