Ok a little back story. This was a dog house originally and I've been slowly turning it into a coop. I've added the vent, flooring, and door. The actually opening for the chickens to come in and out is too big, I know. I'll be adding an automatic door with some plywood to fix it. I have chalked all the little cracks and etc to minimize drafts. I'm thinking about adding some insulation to the roof and it's on a stand that will serve as extra room for the run. I have to finish the roost (which I still need ideas for). It'll be for a max of 5 chickens.
