Since I want to get a heritage turkey and I'm so protective of my birds that I don't let them out unless I am home I am going to have to rebuild my turkey cage. I currently have an eight foot by eight foot cage with a small house it is only about 4 feet high, maybe a little more. I want to rebuild and go 8x8 and between 6 and 8 feet high and build a bigger house then what I have. Since I am going to go higher I was thinking of putting a roost outside and one inside. How high should they be?
