Hi there. We have 7 (6) week old chicks. We think that they are all hens (so far) There are 2 r.i.reds,1 barred rock,1 black sex link,1 black australorp which are doing well. We also have two ameracaunas. Both seem to be having a rough time feathering out on thier backs and one of them smells horrible. She seems to have a small amount of clear discharge coming from her nostrils which she wipes off in the bedding frequently. Can anyone suggest any natural remedies for this "stinky girl"? I've heard of coryza and think that is what it might be. Should we separate her? Will this kill her or spread to the other chicks? Too many questions....PLEASE HELP!
