This is my little four year old broody hen. All of a sudden she looks horrible, puffed up, pale comb, lite greenish poop around the vent, eating little and acting lathergic. I also noticed she has black scaled on her legs. I put her in the other end of the coop and placed a heat lamp on her. I live in Mt where it is around 20 today. Anything I can give her? Natural cider? Please help or I could lose her. Thanks!
