Forgive me if this has been asked before.... Does anyone cover thier run in the winter? I only have 4 chickens, and 3 LOVE to be outside. They even prefer to sleep outside, which on colder nights I go out and carry them into the coop. The coop and run are really sheltered by a huge maple tree. However, in the winter with no leaves on the tree, the snow with hit the run. I am thinking of covering the top and a couple sides, where the wind comes from that direction. Anyone else do this? That way on days it's not TOO frigid, they can go outside.
