This year I decided to make my chickens a little greenhouse to play in on those cold winter days that they don't want to venture into the snow. I took a 8 x 6 cage I had bought when I was having a predator problem and set it on gravel up against the pop door. I then ordered a remnant of 6 mil greenhouse poly and wrapped it in that. I put a bale of hay on the floor. I hate to see them sitting in a dark coop for the whole month of January. Hopefully this holds up all winter because I really think they'll enjoy it!
