I was hoping someone would answer you by now. Being new to raising turkeys you don't want to waste money or growing time on a feed that won't achieve the desired results. My two are 24 weeks old, and are due to be butchered Thanksgiving week. That would make them just shy of 27 weeks old, so, from what I've read, the Tom may dress out at about 15 pounds. That really disappoints me. I usually roast a 22 lb turkey for my family, and was under the impression that all turkeys are dressed weight of 20 or better by now, but, I didn't do enough research, and bought two Bourbon reds, which don't reach a good size and weight til much older than mine are. Ah well, live and learn. Next time I will either start earlier or get a broad breasted breed.
