I have 2 Royal palm Turkeys. We are building thier coop this weekend. I was wondering...am I building it big enough?? It will be 6ftx6ft, and 6ft tall. Thier run will be about 10x10 and covered. Will this be big anough for them to be comfortable? How high should we put the inside roost...and will they use it?? Never built for turkeys before, and I want Adam and Eve to be comfortable!
