Don't know if anyone is still reading this, but I determined the cause of my hen's frostbite was because she dipped her head repeatedly in the water to drink, her wattle was wet, and it was 18 degrees below zero most of the day and they were all out in the dry, covered, tarped-for-wind run with lots of wind breaks and hiding spots and deep dry straw and nice dry dirt... It was bound to freeze with 18 below. Maybe if I had locked them inside the whole day and turned on the heat lamp, I would've avoided it, too. I learn something every darn day about these birds.
The combs are another story.....I can't speak to them.
But my experience taught me that wet is the cause of the frostbite in my hen.
I have ordered a drip system. This will never happen again due to a wet wattle!
AND I found a no-peck-ointment as since I've been watching this bird so diligently and having to treat her 3 times a day, I notice that the other birds are attracted to her PINK tailless tail and when she gets a fuzz feather, they peck it out....my neighbor told me the miracle of this stuff and gave me her bottle.
So now chickie has white wattles (her infection prevention topical for the frostbite...which the other birds also noticed right away!!!! I took their mind off her with mealworms until it absorbed) and a dark purple tail. I hope she's enjoying her NSAIDS the vet put her on, too!
