Hey. This is my first year keeping chickens and I am in ND, where winters get cold. This past week, we finally got snow that sticks and temps that are staying below freezing. This morning, I went out to the run and my Barred Rock's comb looked like it was dusted white. She is still laying and seems otherwise healthy, so I wondered if it was frostbite? Although, I've always heard that frostbite is black. Anyways, I went out and got some Vasoline to put on all of the combs to help prevent frostbite and when I got back, her comb was red again... but then when I went to put the jelly on it, I saw it was red because it was weeping blood. Her head feathers are also stained with blood, so I don't know if the others pecked it or what. Anyways, I am wondering if I should do anything other than the vasoline while it heals and to further prevent cold damage. I'm also wondering if I have it right and this is indeed frostbite/related to cold. The other part of my question is if I should do anything to help with the cold. I already have straw bales piled around the coop and run to insulate and block wind. I also have a little "shack" for them, which is like a 3-walled mini coop. The run is covered so the ground in there is protected from snow and there are roosts in there as well. I have read that you shouldn't provide a heat lamp in the coop because of fire hazard and because if you lose power, the chickens won't be used to dealing without the heat and could freeze as a result. Would the same idea apply to having a heat lamp in the run, that they could opt into during the day, much in the same way I put blocks of ice out in the summer? Or is there no point in it. Thanks for any help. I just really want to do whatever is best for the chickens during our brutal winter. It's only November and we have a long ways to go.
