my production roos that I had last winter got swollen combs that healed by themselves so it might not be too late.My birds had a bad night. They were doing so well, then it got REALLY cold last night. All my roos don't look so good. Swollen combs and wattles. They had plenty of ventilation, and not a lot of drafts, but it was just too cold. I have the worst of them in the basement now to wait out the rest of the cold snap, but it is definitely a case of too little, too late. btw..hens and turkeys are just fine. Turkeys even slept outside last night.
