Help!! My 1.5 year old hen seems to have yellowing of the face and her comb and wattles as well. Has gotten worse the last 2/3 days. Still eating and drinking (from what I can see), but she does seem a bit lethargic (nothing crazy).. She had a really bad molt in September/November and has finally grown feathers back but has yet to lay an egg. Her feet are ice cold, could this be a reaction to the cold weather? It has been in the teens at some days.. Could she be anemic? if so how do I help her??? Checked for mites and she seems clean, same with the rest of the flock. Here are some pictures
