Now that I have a couple of heritage turkeys ( slate and bourbon) I can see that raising the midgets are going to be the best, at least for us.
The full size ones, take forever to get to full weight, and eat a lot to get there.
We did keep them with the chickens, but the size difference made for some bad situations for the chickens. They were inadvertently run over all the time, and any time one of the turkeys beat its wings, any chicken in its path, took a sever beating.
We lost on hen due to this
