I have chicks that i hatched this early spring, and I have quite a few roos, just wondering what you would reccomend feeding them to fatten them up for butchering in the fall. They are just plain ole backyard flock mix, no broilers or anything, but i would like to have a few in the freezer. I have layer hens right now, and feed layer...of course. but i have them in a seperate pen from the roos. So I can give special feed to the roos if needed. Any suggestions?
