We ended up putting a thick rubber mat in the coop bottom to block the cold in the winter. They seem to love the area. We have also ramped the entrance into the coop although they didn't seem to have any problems with it. (The chickens are above with the same set up. The duck nesting box extends out the other side into the chicken run. Each coop is 4x4x8. Each run is 10x20. We are going to try and let them out in the yard during the day when we are home. We also ran drainage under the coop for the pond with a sink trap in the bottom. When we drain the pond (about every 2 weeks) we catch the water in a large rain barrel and use it on the flower gardens.
