I had figured on making a standard little roost house for my bantams but they've thrown me a bit of a curve. At the moment all chickens are in what is basically a run in shed (was a stable with a loft but someone converted it to be an open door vehicle port of sorts. We have wire across the front to keep out predators. THe space is divided to keep the large breed chickens on one side while the bantams (all hens) are on the other with the ducks and geese. THey had been on a roosting/feeding board but now my Dutch bantams have taken to roosting in the rafters about 10 feet overhead while the cochin is down much lower. With our winter temps in PA being anywhere from the 20's to below zero, I don't think the Dutch bantams are suited for that (in my opinion). I can't put them into the new chicken house (enclosed) for the large breed as they get attacked. What is my best recourse to induce the "high fliers" and my cochin to take up residence in a lower structure? Or what are my options for small scale winter housing (rapidly approaching!!) Thanks!
