Id like to get Cornish hatching eggs or chicks at least but dang you have to find a breeder. I like the red patterned looking one..? The Cornish cross has literally drove the breed that it came from into the ground.
My white leghorns are fine with the snow. I live in the mountains of TN. And white leghorns are amazing with heat because of their big floppy combs. But as a side comment. I agree with people here. You would need two types of chickens. The phrase dual purpose can be misleading. Most of the time...
