UPDATE:
Well, we brought our rooster inside for the day and let him get warm in the dog crate. And now, I'm happy to report, he's doing fine. Crowing and strutting, altho I haven't noticed whether he's mating.
ONLY NOW, one of our hens just died. 2 years old, the one in the avatar, which is going over like a lead balloon with the broken heart who's holding her, she started acting lethargic the past few days also.
I partially blame our continuing arctic-like cold conditions here, bitter winds, and temperatures still hovering right around freezing during the day, which is unseasonably cold. It's so aggravating, because I feel like if Puffy had not been so cold, she could have recovered like the rooster did.
Anyway, I'm wondering if they might have eaten the styrofoam which has re-appeared from under the snow - I guess I put it out for the garbage and then the snow came in the fall and never left, and now there it is again, only it's all pecked. I brought what I could inside until trash day, but there are still pieces of it stuck in snow that I can't get out, so I'm trying to keep the chickens away from it.
Does anyone know if styrofoam kills chickens? I wouldn't be surprised.
The other 8 hens and the rooster appear to be doing fine. It's still blustery cold out, but someday it just has to warm up so I can spend time out there and get a good look at all of them and clean their coop, etc.
Puffy, by the way, my 2 yr. old hen, was a frozen solid lump on the coop floor this morning. First time I've had to deal with a dead chicken. It was not pleasant. I covered her with hay just so I could shovel her into the wheelbarrow without having to see too much of her. I'm a wimp, but you have to develop a crust for these things, hopefully the crust will come. I'm sure she won't be the last chicken who dies.
I'm so mad at this cold weather. It's bordering on ridiculous.
