I am picking up 3 heritage breed turkeys this weekend to finish off for t-giving (all were March hatches). This is my first time with turkeys ( keep chickens and quail at the moment). I have a big tractor ready for them so they can enjoy some grass. I wish I could let them free range all day but we are having a massive hawk/fox/coon/coyote/you name it problem right now and I need to keep everyone safe. (Everyone is free ranged though when I am home under direct supervision). What would you recommend for a good feed to finish off these guys? I have Southern States, Culpeper feeds and Blue Seal available, as well as lots of 'grain' options (I could do a mix). There is also a Purina dealer but it's very pricey. Thanks for any input!
