We feed Homestead Turkey Starter for 10 weeks then Homestead Fast Grow o finish them. Both feeds are made by Hubbard Feeds and we have had great success with them.
26% chick starter mixed with scratch and then throw in a couple handfulls of meal worms. They also get lots of boiled eggs and vitamins added to their water. Seems to work pretty good!
28% medicated game bird starter until about 16 weeks then 20% medicated start n grow until they go out with the flocks about 5 to 6 months old.
We have our feed special mixed at a local feed mill and the "regular" feed is an 18% protein with 150 pounds of oyster shell mixed in per ton. Yes we buy chicken feed by the ton - our feed mill guy loves us
During breeding/egg laying season we up the protien to 20%
