I feed a protein pellet corn mixtureof 16% from a free choice feeder. I also have a feeder that slings corn at the same feed station. The larger bucks walk in the pen and hit the protein feeder till they are full then mosey off.The other deer eat the corn off the ground. EXCEPTION: Several of the older does will eat from the protien feeder like the gluttens they are till they roll over from bloat or gun shot wound to the head.
