Many things I've read list Leghorns as not cold hardy. I have White Leghorns, and live in Minnesota, and they do fine. They don't lay much during the winter, like most breeds, though. My Pet Chicken, however, lists White Leghorns as cold hardy, but non-white varieties as not. I want to purchase Light Brown Leghorns next year, so am wondering if anyone knows or have had experience, with non-white Leghorns as being cold hardy. Thanks in advance.
