You are NOT helping these deer! Soooo many people have this misconception. Deer are acustomed to eating woody vegetaion in the winter. Feeding them oats, corn and hay, can KILL THEM. Their bacterial colonies in their stomachs cannot digest this food durring this time of the year. They will DIE with a full stomach, because they cannot digest the food! If you REALLY care about these deer, do them a favor! STOP FEEDING THEM!
