We are new chicken owners, and have a small flock of 6 chickens. They are almost 5 weeks old and are still inside the house, but will be moved out to their coop this weekend. All six of the chickens had developed little combs on their heads. This evening we noticed that the comb on one of the chickens is totally gone, it looks like it broke off.... it is almost like when you break a piece of candy corn in half (that sort of breakage texture). Upon noticing this, we also noticed that another one of the chickens has redness around it's comb as though it has been picked at. Is there some sort of comb disease, or do I have hens bulling each other? They are all the same size (roundabout) and I don't think anyone is a rooster. I just can't figure it out. Does anyone have any insight/advice?
