OK I have looked everywhere and my questions have not been answered fully yet. I hope that I'm not just missing something. It is VERY cold here in Arkansas (for us) and my chickens aren't used to that. I am hoping that they are just suffering from dry skin. My roo has black and a few whitish spots on his comb. Due to the whitish ones I don't think he has been attacked. Also he is VERY dominant to all of the birds that are with him so I don't think that's the problem. HIs spots aren't wet, raised, or totally gross looking if that helps. I read that it might be due to lice or mites but I haven't found any pics to compare to or much info that goes along with that supposition. It probably is time to treat again with DE but it hasn't been that long ago since I treated them. Wouldn't they have to have a large outbreak before they attacked their combs? I hope I'm not going on too long I just want to find out what's wrong and I really don't want it to be anything too serious. Sometimes it feels like someone is always needing extra care
