I don' t now where your from blades, but feeding deer can do them more harm than good. Take corn for example. Deer that are not used to it can build up excess lactic acid causing arthritic symtoms. Some get severe diarrhea. Some may even die. All because its not part of their natual diet. Not to mention the diseases that can spread from close contact around your little " feed lot" . Do the deer a favor and let them survive on their own. Or at least talk to your DNR biologist so you don' t do more harm than good.
