If you had started them on wild game starter then at 2 1/2 month or 10 weeks period. They should be starting to switch from starter and on a grower mix now, 20 to 25 %. But they could still handle the starter. With the BB's you don't want them to grow to fast, as that adds to the risk of leg problems.
You would want them on a wild game bird feed, there is Extra minerals and vitemans in this feed mix to help Turkeys grow. Game bird stater has grit already in it, but it's small grit. So at 8 ro 9 weeks or so it's a good idea to add larger grit. Even if they got a slow start on the chick starter, by thanksgiving the male could go 25 to 30 lbs dressed. If your feed store only has wild game starter and they are ready for grower, you can cut the starter with oats or chicken scratch, try the oats first.
If they show any signs of leg problems, such as a wobbly walking , any sort of a limp, crocked legs, you need to add soulable vitamins to there water. Usually any generaric type will work. (one of our vets, was an inspector at a poultry processing plant some time ago, and suggested that to us). With the exception of grass don't add any thing to there feed like oyster shells or table scraps until they are close to there mature age at 30 weeks.
After 10 weeks it so much easier to have them outside vs inside, as it takes a lot less cleaning.
