I noticed today a few of the girls have a bit of white around their combs, these girls don't have particularly bright or dark combs anyway, and it's not even that cold inside the coop. With the weather outside at -17 today the coop inside was coming from 0 to -5. What do you guys think? Should I get me some vaseline and/or a ceramic heat bulb. I just don't want to heat, they're supposed to be a cold hardy cross breed and I don't want to make them wimps by heating the place. The coop is insulated though not massively, is there anything else I can do? Otherwise they're fine, no one has lost toes, no one seems cold. They're all busy and acting as usual. Thing is, I've never seen frostbite before, and It just looks like they were outside in the cold too long, like when you don't wear mittens and your fingers go red at the ends? I'm going to pick up some vaseline tomorrow anyway just so I have it.
