I'm somewhat of an amature... First winter with chickens. I have five (soon to be eight this spring). I'm in the d/fw area. I built a really good coop. If you live here you know it has not been cold yet. What do i do about closing some of the vents (to keep the coop warmer)?. My coop has two windows and vents at the roof of the coop. I have closed one of the windows by about 70% (it faces South). I don't see freezing temps in at least 10 days. Would the chicks survive with the windows all open? my coop is 4x6 with a run about 75 sf. we let them free-range in our backyard from about 2:00pm until they decide to go in for the night. Please help!! I am interested in talking to others from the metroplex!!!
