first off, a lot comes down to here you live as many states it is ILLEGAL to feed them
so, if you happen tom live where its legal
yes and NO you can feed deer
I think most folks are better off NOT doing so
all wildlife has its own ways to survive when humans step in it can cause them to alter there patterns,, eat things that MAKE them feel FULL when there not and thus cause them to suffer
that being said, IMO< the other side of this coin is, YES you can also feed them, BUT if you start, you need to continue all winter till green up
don't get them coming to your place for easy meals and then cut them off mid winter!
another DOWN side to feeding deer , is when you feed foods to animals making them group up and eat from same piles or feeders, it has been known to cause the spread of illness to deer when or if a sick deer eats from there and then others eat contaminated foods the sick deer maybe drooled on or other wise ??
another thing is just keeping your feed from spoiling, corn dumped on the ground can get moldy pretty darn fast and then things that eat enough of it can get sick or worse?
other foods too can go bad laying about
good intentions many times turn into BAD results
wild animals know how to survive in all but extreme conditions and well then that is mother natures way of making the strong survive and weed out the weak!
cruel at times, but the natural cycle of things
