I have a white Cochin bantam chicken who is around a year old. She has a very pale comb. She is skinny. She moves around and comes running when you call but she spends a bunch of time sleeping, I recently wormed her with 1/4 cc of Valbazen and then waited 10 days and gave her another 1/4 cc. She is also still laying does any one have any idea what could be wrong with her?
