Sometime this week I will be getting two young silkies; I have plenty of regular chickens, but I have never kept silkies. I have this coop. http://www.tractorsupply.com/en/sto...heavy-duty-chick-n-hutch-2-4-chicken-capacity I am wondering if it will work for them during the winter. It will be just the two silkies in it and the the whole front of the coop is just wire. The weather where I live (Tennessee) isn't too bad and it most likely won't get below 0 but it will get to the 15-20s several times throughout the winter. Would this coop be too cold for them? Do I need to put wood across the front so it will be warmer for them? Any other silkie advice would also be appreciated! Thanks!
