Hello, I'm a little worried. We bought two chickens this weekend and when we got them home we noticed one had a bald patch around the vent and underneath. This seems to be red and chapped in places. She is also sneezing a few times a day and has a slightly crusty nostril. Also every so often she stumbles. However she is very alert, still laying eggs and always hungry and eating. Could this be caused by the stress of rehoming? We have put lice and mite powder in bedding as she prefers to sit in nesting boxes. She is being fed grit, layers pellets and pellets recomended by breeder. The other hen is fine and they both came from same pen. Help me please Lucy
