My one year old RIR hen is sick. She has lost weight, has diarreah, her comb is a purplish red and she is very weak. I have not been able to see her eat but usually has layer crumbles and cracked corn. Up untill a week ago, they were all running free but since the two 9 month old puppies came, they have been penned except for an hour or so at night, just before they roost. Any ideas?
