In many areas chickens and turkeys have to be raised separately to prevent the turkeys from getting blackhead which can be passed to the turkeys by the chickens.
If you have a group of toms only, with chickens when breeding season arrives, you will end up with flat chickens from the toms trying...
If you want to keep your chickens alive, you will not put any of them in with the group of toms. The only time that chickens can be considered of value for teaching turkeys is when a chick or two is put in a brooder with day old poults.
My recommendation is to either sell, rehome or process...
