We have had some very cold nights. Our coop is dry and relatively draft free, accommodating ventilation needs. A few of our hens have frostbite on their wattles from dipping into the water bowl to drink. Today I noticed one of them, who seemed to have it worse than the others, has swelling between her wattles under her beak, causing her wattles to stick out instead of hang down. Does this mean she has some sort of infection, secondary to the frostbite? No other symptoms. She appears to be eating and drinking, though I noticed it towards the end of the day when less eating is taking place, and I didn't think to check if her crop was full. What can we/should we do for her? We were going to bring her inside to a crate for the night, but she is tucked in between the others roosting, with her head facing away from the closed windows, so I honestly think shell be warmer with the flock than in the garage alone. I did give her some VetRX by mouth. We had a night that was -6 F a couple days ago, with the days staying below freezing.
