Let's say I eat 50 chickens in a year, and I want to raise the meat myself. I can't have them all at the same time, because it'll be a bit much for me, I think, and I don't have freezer space for 50 chickens. I'd do a rotation, but it gets quite cold. How much cold can five-week old chickens handle? Edit: Say it's they dead of winter and there's outside with a heat lamp, and protected from snow and wind. Are they all right?
