Hmmm, the inactivity theory is interesting... I've always let my turkeys freely range over the acreage here, and this is the first year I've used the movable fence system. I hadn't thought about it before, but you're right, that my birds wouldn't have been getting nearly the same amount of excercise as they used to since they only have so many hundred square feet now to range versus acres and acres. Can anyone else verify or dispute this theory? How active/nonactive are your heritage turkeys and did they have a lot of fat on them? (not asking about BBWs here, just heritage breeds). Thanks!
