Our chickens have had small spots on the comb, which we thought were due to pecking, but now this one is much pronounced and concentrated in one area. Could this be a disease and potentially contagious?
We have 4 Dominique and 4 Australorp hens, 6 months old. We noticed black spots on their combs recently. Is this something to be worried about? What do we need to do to get rid of the spots (if they are bad for the hens)?
