Here I don't make the first cut on the pasture until May. In Spring they are nesting in the tall fescue. Chufas are a good plot as well. Warm season here they usually have grasshoppers and fescue seed in their craw. Cool season. Sumac leaves, honesuckle leaves, chufa beans, brasicas, clover and pin oaks. Cattle pasture and deer plots are both perfect for turkey. As the gentleman above said they forage for the bugs. Cooler season they eat the vegetation. Cattle pasture same thing and they scratch the cow pies to eat the red worms that come out of the ground to eat the manure. A good creak or pond is essential as well.
