I foolishly ordered two Sicilian Buttercups without reading up on them first. I'm Sicilian and couldn't resist. But now that my impulsiveness has worn off, I'm concerned about the cold winters we have here in New York State. I know, I know.....dumb right. Anyway, just how low a temp can these beautiful Sicilian girls tolerate? We don't plan on heating the coop and it's well built, draft free, but not insulated. This is my first time raising chickens so I don't know just how cold the coop will get. Our garage gets down to about 52 degrees so I'm guessing the coop will be similar. That's of course if we have a mostly mild winter. Any suggestions?
