That is a good question. I just keep a feeder full for mine during spring lock up. I also throw them a lot of scratch and food scraps to keep them busy. I even visit them during the day. My turkeys are weird. they spend most of the day socializing even while free ranging. They do not really eat at chicken TV hour either. They just come to visit. I sometimes wonder why JJ has not starved to death, he never seems to eat. just gobble and talk to me. I even opened up some old straw bales for Ethel and her chicks that had nice big grub worms in them, they ignored the grubs, which is weird because chickens would have gone nuts over them. The turkeys seem content to just nibble on grass in the yard.
