Thank you LM. My boys have the same color and more of it. Their wattles are also very very swollen. The only pictures I've seen that come close are pictures of coryza but it's not that. There are no respiratory issues at all and it happens overnight.
One bantam male has it on one wattle (the side facing the coop door) which I have subsequently closed.
I will try try to get pictures tomorrow and I can promise you, they will make you cringe.
The feed pans might be an issue with some of them but the one that is the worst has a feed pan only about 3" wide, maybe a little more. When I've watched him eat, his wattles would still be outside the dish so not laying in the ff. Maybe I can get a narrower dish for them anyway and see if it helps.
Tomorrow though, I think I'm going to be bringing roosters in the house to feed them and get some moisture to them. They'll go back out and depending on the temperature and any wind, I may or may not keep their coops closed.
Did you see the post from Alaskan abut using plastic instead of metal pans? Metal transfers cold and causes frostbit.
I am not going to use a heat lamp tonight,but am debating about tomorrow. My reluctance is this the concern of frost bite due to increased humidity. Last cold snap I panicked some (first winter with chickens) threw in not one but two Infared lamps. Ended up with frost bite on one of our Wellies comb. She healed fine, wasn't too bad. Anyway, I have since done a bunch more reading and the bigger concern is humidity. Our coop isn't air tight as it was an old shed converted, so it is insulated probably 20+ years ago. We have venting at the top of the coop for moisture to escape, the coop venting faces north and our winds run north to south usually and east a lot. We have three roosting bars for the gang, deep litter method about 4 ft currently on bottom of coop, 25 birds all cold hardy.
