The feed store where I worked the #1 feed sold for animals were deer.We mixed our own feed.and the super 6 is primarily for bone develpoment in cattle and horses.Our customers including myself use the stuff for deer because it seemed to help.Plus if we thought that the deer were pests.Then why would more than half of the workers are deer hunters.I agree tha some Co-op's are that way.But do not generalize all feed stores.
