Im planing on moving my birds to a new building next year. The building is 25x25 ft with a loft. I was thinking of doing a run 25x50 ft. It was going to be for silkies only. I am now thinking of moving my layers into the building. My layers are free range though. I do not want to free range the silkies but i do want to have a run for them. How can i blend them? I just need nest boxes for the layers but need lots of space for the silkies. Any ideas? This was an old two car garage so it has two large sliding doors.
