Hi i'm new to the message board and new to chickens as well. This will be my first winter with them and I have 6 golden laced wyandotte hens and live in Minnesota. I built the coop with 1.5" foam insulation sandwiched between plywood to try and keep the cold out a bit. I have read some posts that say you shouldn't heat a coop...because if the heat goes out in the winter they may all die. And some that say you should. I was just wondering what peoples experiences were in colder climates. Also... I did take a line voltage thermostat and rig it to a heat lamp in the coop.. ( 4 x 6 feet coop ) so if it drops below 35ish degrees it should click on the bulb. But now that I have i'm sitting here thinking... chickens make a lot of dust.... has anyone ever heard of a chicken coop explosion?
