My coop is the "tangled nest" the coop is elevated about 2 1/2' feet off the ground and there is quarter inch hardwire mesh under it. There's a 1x1' hole in the middle of the coop. Out side i have a decent size run. I keep the water in the coop. I don't know how to let them out and keep them warm at the same time. The coop is usaly the temp outside inside last winter my rooster lost the tips of his comb and the others had other frostbite damage. I want atleast let them out in the little pen under the coop. Im going to buy 2 straw bales and put them infront of the little pen to atleast keep all the wind out. Is insulating it worth it? We could heat it we choose not to because the negatives out weigh the benifits.
