Clover is GREAT for turkeys. In the fall, there is plenty of seed and corn for them. Winter time with plenty of snow would be the only time there maybe a stress period. If there is cattle around, then the farmers will feed the cattle hay and alfalfa so the turkeys can get seeds and protein from that. The guys from Wisconsin, Minnesota, North Dakota and the UP of Michigan may chime in with some snow and cold temp advice. Brutal winter there last winter.
