You are probably right there Tam. Actually though I found that when it comes to turkeys, the higher the protein content the better my birds turn out when it comes to pushing them. Honestly though, my turkeys run on a lot of ground so once they are full grown, they only get strait shell corn. I supplement them with a protein supplement in the winter only. We have several orchards that are fenced in that we run our turkeys on, so they clean up all the bugs and get to enjoy any fruit that hits the ground. My turkeys are only started on a rat wire bottom pen for the fist month, then they go straight to the dirt bottom floor. One fun thing that I do that seems to greatly help with nutrients the turkeys get during their developmental stage is placing a bright floodlight outside in the pens to attract bugs all night. It's an all night buffet and when the June bugs emerge, WATCH OUT!
