Yep, my poor husband. We changed our roost three times We now have a 2 x 4, long side flat up so they can cover their toes. We have ventilation up high and can close their door. We also have tarps that we can hang on the outside of the run (a 10 x 10 dog run) to keep snow from getting in and it help keeps wind down. The run has our garage on one side (6 inches away) and part of our house is on another side (several feet away) so they have a good wind break anyway. It can get in the single digits here on the coldest days in the early morning hours.
