Hey all this is our first winter with chickens... as you can read by my signature, we have a variety. Our coop is a 10 x 12 wooden shed Directly across from the open door is an automatic coop door which operates with the sunlight. During the summer months I usually have both of the front doors open as well. When it started getting cooler, I shut one of the doors and today both the front doors are shut since its running 43 in PA. Directly behind the chicken sign is a 3 x 10 portion that is screened off for a brooder and my two baby peeps (3 weeks old) are with a heat lamp. The structure is pretty sound and draft free - with the exception of the auto coop door. What do others do in the winter months? Do you keep the auto coop door active?? Do you put some type of material - like those freezer plastics on the inside of the coop door to keep some of the wind out of the coop or do the chickens stay inside all the time when it gets really cold? I use the deep litter method for bedding. I can just tell I'm going to be a worry wort that they will get cold! I've already ran home to make sure the peeps are warm enough - they weren't so I lowered the heat lamp a bit. Any thoughts? Please and thank you in advance!
