I have a turkey i am showing at the fair (in 2 weeks) and he is several pounds under weight. He is 21 pounds and the minimum is 25, but ideally 30 lb is the best. He's 12 weeks ( give or take a few ) old and i am feeding him some cracked corn along with pellets. Any idea what he will gain in 2 weeks? Any Help/Tips appreciated! Thank you in advance..
