My BJG (which I have since lost to a coyote ), had an enormous comb and majestic wattles. He lost much of both to frostbite his first winter, which was brutal (2020/21, which was when a lot of TX also got shut down due to ice and cold). He was definitely in pain. He could not eat from the feeder, which has 3" PVC openings, without scraping both comb and wattles on the PVC. We fed him separately from a flat dish. Not much we could do about the water. His wattles dangled in the water and got wet, the temps were brutal and never let up. He became very much a pet, knowing that his food came from us and not a feeder. I do miss him. No bird should be considered "cold hardy" if it has large comb and wattles, IMO. I love BJGs but will never have another in this climate. Our winters are not long but they can be severe.
