We've had unusually cold weather this week. Tuesday night, when we were closing up the chickens, we noticed our rooster had iced feathers on his chest. It looked like he had gotten wet from his wattles while drinking. We brought him in the garage and placed a heat lamp on him to keep him above freezing temps. We also noticed his wattles were pale and frostbitten, with a bit of swelling at the bottom of one. The next morning we discovered his wattles and chin were completely swollen, and he wouldn't/couldn't eat or drink. Here is a photo I found from a previous thread on BYC that looks just like him: It's horrible and he has to be in terrible pain. Yesterday, we had him under a heat lamp all day, and had to give him electrolyte water with a syringe, along with some runny yogurt. There is no improvement today, although he's still crowing. He hasn't had & still doesn't have respiratory symptoms. Questions: Is this frostbite? If this is cholera and he recovers he will be a carrier that infects our other chickens, correct? In that case, it would be better to cull him. I don't want to see him suffer any longer if that's the case. We're planning on starting Duramycin-10 in water with his syringe this morning. Is that the best thing is this is simply a secondary frostbite infection? Has anyone seen this in their chicken and had them recover? Again, is he's just going to suffer and then die, I'd rather put him out of his misery now. Thank you for any help you give us. We are heartbroken to see him like this and not know what to do. Our other rooster has been frostbitten, but we've never seen anything like this.
