I cleaned the pooh from my hen's vent because it was hard and I didn't want to encourage parasites. I used warm water and got most of it off. I was gentle with her but had to tilt her on her back and keep a firm hold. When I released her she didn't move - just stood for a good long while, then sat. She hardly moved for the rest of the day, and when she did she creeped along as if in discomfort. I noticed she has a swelling below her vent. I am frightened that I have damaged her when cleaning her and perhaps broken an egg inside her? I have brought her inside for the night. Her breathing is audible and I have sat her on a towel with a hot water bottle underneath. I have not got calcium tablets yet - will get these in the morning. She has taken no food and little water from a pipette. Does this sound like an egg is broken inside to any of you more experienced chicken keepers?
