Got a little button buck that I raised from a tiny fawn. He's in a smaller pen now but we're building a big one in the spring and gonna get a few more deer. His buttons are huge looks to have good genes. Anyone have any suggestions on what to feed him? I just been giving him corn and calf feed for now and he loves it. His body is filling out well. Lookin to see what grain I should be giving him. Thanks in advance for any help
