I got 6 day old Turkeys from my local Agway in the beginning of July. I was concerned about getting them in July & them being big enough in time for slaughter, but for some reason they don't sell them around here until then. Are they going to be big enough? They are on grower feed but I will be switching them to a specific Turkey grower feed soon. I have no idea what kind. I'm assuming a what ever white commercial type turkeys are.
