I apologize if this question/ concern had been asked.... I have a 6 day old chick who has developed a swollen vent which smells awful as well and a loss of feathers around the vent. The chick has been chirping like crazy and has been active. We have been washing its butt in warm water but are very concerned. The chick is with 3 others and the hen who hatched them. They have fresh shavings and water and food daily. Thanks in advance.
