My one year old hen has recently become ill, her comb and wattle are a yellow orange color and her skin is yellow. She is dehydrated and not eating- She is thin and her feathers are falling out (molting more than ususal) and has scaley flacky skin. I seperated her from the other and have her in a warm place with vitamin water and food. She's taken a little water and a few bites of banana and egg but doens't look so good- poor thing. Does anyone have an idea what she might have and what I should do for her. The other hens are fine- no symptoms.
