A few days ago I noticed my RIR hen. She is all fluffed in the feathers. Some poop was tuck to her bum. It was yellowish and VERY smelly. I found her standing in one of the nest boxes sleeping in the middle of the afternoon. Her vent was ok. It looked normal, not blocked or anything. I isolated her. Gave her some water with apple cidar vinegar in case of yeast infection. I also gave her some feed crumbles with Epsom salt to halp as a laxative. She immediately started drinking and feeding. She has been drinking alot! It has been one day of treatment. She is still alive but no real change in her condition. She is about 1.5 years old. No sign of problems with her other 49 sisters and one brother. My next move may be to deworm her. I can post pics tomorrow if it will help. Kinda late and dark now. Any thoughts out there?
