How did everyone's chickens weather the cold? My girls did surprisingly well despite the -10 temps! They all came out with some frost on their feathers and one actually had 2 chunks of ice on her feathers! But I don't see any signs of frostbite on combs or wattles.
They certainly don't care for the cold weather, although they seem to tolerate it fine! Right now they are hanging out in the sun and all frost/ice has melted off. They are all fluffed up, some sitting on their toes to keep them warm, others doing a one-leg stand. LOL I am buying a heat lamp ASAP because I can see that this winter is going to be bitter! I'll probably only turn it on for next below zero, though.
I don't know anything about Vaseline and haven't ever used it, although I have read about it. From what I understand, cold temps aren't the trouble with frostbite, it's the moisture/humidity. If the coop is well ventilated the moisture that they breathe out and poop can dry out and they won't get frostbite. If the humidity gets too high, though, that's when you have problems. I believe the Vaseline provides a barrier to keep the moisture in the air off of the comb and wattles. I have, however, heard of people saying their birds made a huge mess by rubbing their faces in dirt or sand and having it stick to the Vaseline!
I am grateful that CO has generally dry humidity! It really helps in keeping the coop dry! It's supposed to be in the low teens tonight but I figure after -10 last night, it'll feel like a day at the spa for them!
