Chicken Breed Focus - Sicillian Buttercup

[MissLavender]

I live in northern AZ and am considering getting a couple of these. How do they do in the cold? It gets down into the high teens/low 20's at night here in January/February and I don't use heat lamps. Also, how are they as laying hens?

They are such a underrated breed!
