I recenly got two, two week old chicks and one is doing great. Eats, drinks, is healthy, and growing fine but her sister is not doing so well. We first realized she was sick when she pooped blood one day. She stopped eating and drinking and is pretty weak. We keep their pen's temperature around 80 degrees and have been giving her water/chick feed through a dropper which seems to help some because she hasn't had anymore blood but she still has another big problem. She has developed a large, dark lump on the right side of her breast. It's filled with a liquid and we have no clue what it is. It doesn't seem to hurt her when it's touched but she is very weak and not eating. Were sure she's going to die if we don't do something soon and I'm open to ALL suggestions so PLEASE HELP! I can post pictures of it if that would help any.
