Stick with soybeans. It has a 32 to 38 percent crude protein level. I never go with commercial mixes because, well, soybeans do better and are usually cheaper. Numerous published research papers have proven this fact. They also hold up well to moisture. Many commercial pellets act like sponges and end up growing more mold. It will take a little while to get deer acclimated to soybeans, but when they do they will keep feeding on them. Deer do not gorge soybeans as they do corn and non-target species like coons and birds eat very little. As for corn, it is highly digestible as it is a carbohydrate, mainly a simple sugar (glucose or sucrose). It has a 8 to 12 percent protein content. It is not very good for deer. It's better to fertilize natural browse than feed corn.
