Hi all! First time chicken keeper here, making this our first winter with them in VT. We've had colder snaps, but my chickens seem to be suffering with frostbite since yesterday's freezing temps. I've seen pictures online of comb frostbite and my chickens combs look different so I'm not sure whether they have an extreme case of it or not. They are all eating and drinking well and are perky. Two have frostbite worse than the others that have created rings on their combs and I'd love your thoughts. Should I expect just the tips to fall off or the whole comb? What's the recovery time? Will they need to be segregated while recovering? (I had to do this after a dog attack so I would like to avoid this at all costs!) I tried coating with Hen Healer but they rub it off. I worry about touching them too much for risk of further injury. Thanks in advance for any insight you can offer!
