Good luck with your chickens. We just started our lil chicken farm last march. I have a total of 26, 22 hens and 4 bantam roos. I was pretty worried about keeping chickens through the winter but we have so far not had one death due to temperatures. Thank Goodness. The neighbors dogs seem to be our only predators so far. We are in Cheyenne. Again good luck! They are so rewarding!
