I have 2 roosters, 3 hens. We've had unusually wet/cold temps this week (8 degrees to 25 degrees) and this afternoon it has finally gotten sunny and warmed up to 50. While cleaning out the coop, I noticed Pecky's comb looks black on the tip, and there is something whitish below his cheeks. I know he and my other rooster have gone at it before, and I'm hoping the black is just dried blood...
