I'm a newbie to the site and an egg-layers only for nearly ten years now. (yes, since I was nine years old). Anyway, I'm in 4-H and have decided to raise some cornish crosses for my siblings and I to enter in the county fair. I'm not quite understanding the start/grow/finish principles and am wondering if they can start/grow on the turkey grower that's available at my supply store (they don't have anything else with high enough protein) and simply mix it with corn or some grain for finishing. I also have questions concerning fleas/mites and bathing because they have to be perfectly clean for the fair.
