Sorry about your sister's dog, Hoppy.
I may try the bag balm, ashandvine. This rooster and I do not get along all that well. If I use it, I will just do his comb tips and maybe some of his wattles. He is in the hoop coop, so he still has access to plenty of dirt. And while it is very cold out there at night, the coop warms up nicely on sunny days, even with the large amount of ventilation.
Even though I am constantly worried about the chickens being too cold, I know that they are very hardy. One winter, on the really cold below zero nights, we got in the habit of shutting the pop doors to conserve heat. Normally, we leave the pop doors open all the time, because the run is super secure. Anyway, DH went out and closed the pop doors for me, since I didn't get home until after dark. The next morning, I went to put water in the run, and there was one of my Welsummers. DH did not realize she was still out there, so she was locked out. She was alone on the outdoor roost, 13 below zero. I was horrified and expected her to be frozen to death, but I picked her up and she was fine. She did shiver a little, but then joined the others for breakfast.
Nice sunset photo, ashandvine! I was actually watching that beautiful sunset too. We don't have a great view of the western sky here, but we were at a friend's house. They have big picture windows facing west and a nice view. It was very pretty and lasted a long time.
