Hi, I didn't post this in emergencies/diseases because I don't think the problem falls under those categories. Anyway, I have a flock of 8 production reds, about 1 1/2 years old. I've had them since the end of August. Today, I noticed a few of them have black smudges on their combs. I've read about dry pox and the description doesn't fit (white, wart like nodules followed by scabbing). It can't be frost bite yet as we haven't had a frost although the temps have gotten down to the 40's a couple of times. No, they just look like black smudges from ashes or something. Any idea what it could be? Thanks!
