I have two chickens that have pasty butts, and there has been some runny poo in the coop and chicken run. I live in the Boston Mass area and the weather hear has been extreme for us almost record setting snow falls, sub zero weather. The coop is heated and I have allowed the girls to go out into the run, but mostly they like to stay in. Anyway, one of the girls is very lethargic, does not appear to be eating. I am going to attach a picture of her butt. My plan is to wash her with dawn dish soap, will this hurt her? Can anyone give me advise on what I should do?
