i could use some help if possible. we purchased 2 rhode island red chicks about a year ago. they both seemed perfectly fine until we got home and was checking them and noticed the smaller of the 2 seemed to have poop stuck on her rear and her rear seemed to be swollen. we were told she probably wouldn't make it but as i said it was a year ago. well we named them so we could basically call them our pets. since they are chickens, we gave them names that fit. legs, who is the oldest by about 2 weeks, is pretty healthy. thighs, well she had the problem when she was little, she apparently didn't get over it. her underside and rear are swollen. she has been laying eggs so i pretty sure thats not her problem. she is eating and all. she seems fine other then the swelling and a limp. she has us worried because as i said they are our pets. please help.
