I have a sick hen. She is hiding in the coop away from the other chickens and i noticed she had egg yolk dripping from her cloaca. I thought she might have a cracked shell inside or be egg bound so i soaked her back end in a nice warm bath and put her in a different coop then her flock. She has not passed anything yet and is still acting sad and lethargic. Any advise is welcome. Thanks in advance.
