I am feeding game bird food crumbles to our turkeys (it is what the breeder feeds them and all his turkeys). He also said to add some cracked corn. Should I do that with every feeding (daily) or stop during the hot temperatures? I know with horses and such, corn is for producing body heat. Does it have the same affect on turkeys? Am I making it harder for them to deal with our awful heat? (eastern missouri, about half way between stl louis and hannibal).
