One of my chickens (almost two years old) is acting strange. When she is standing, her butt is sort of drooping, much like that of a duck. She seperated herself from the others in the flock. She didn't put up too much of a fuss when I picked her up. I gave her a warm soak and she seemed to enjoy it. She has been eating and drinking good (two days in a kennel now) Her poop piles appear normal but smells different than the normal poop. Her eyes and comb are normal. I dont think she is egg bound but hasn't started laying for the spring as of yet ( I'm in southern Maine). Thanks for any advice.
