I have a sweet (usually) 2 1/2 year old BO named Flopsy (her comb falls slightly to the side, not sure why) having butt trouble. Her poop is really runny and is all over her back end, only liquid. None of my birds are laying (recent move, new state, new place, big pole barn previously housed horsed now keeps my flock) she had some trouble like this over the summer and when it was warm I washed her butt outside and trimmed away the feathers that were blocking anything. Since it is now 17 degrees at night I am going to have a heck of a time cleaning her up. She doesn't seem to have any less of an appetite, not lethargic, color is good. So what's wrong with my hen? The ONLY REASON I am posting this under emergencies is because it is very cold out, and she has been roosting about 10 feet in the air and I am hoping she hasn't gotten hurt trying to fly down. The person who had this place before we moved in had chickens at one time, but got rid of them shortly after, and never said why. Could it be my barn causing trouble? I do have heat lamps, and the water is freezing, the feed is the same if that helps. Thank you in advance.
