Well we finished up our coop yesterday and wehn I went out this morning with the door closed all night it wsa nice and comfortable in there. Dark but warm. We took the 6 1/2 wk/olds out there this morning and they love it, more room to roam . Then it decided to rain more than just a sprinkle and I had to run out and shew them inside the coop and close the door off to keep them in. The roof over the run leaks a little, but it keeps most of the rain out. I checked the coop after a heavy downpour and it was dry and that's the main thing.
