They tried to feed elk and deer in Colorado with hay, dumped tons around one particularly harsh winter, but the deer starved even while eating the hay. I think it may not provide what they need - or may puncture them inside, I always saw them eating leaves and live plants when they used to come in the yard. I remember the elk being ok with hay though.
People have good hearts and they mean well. It's too bad it can do more harm than good.
I've got some friends in Sweden who feed deer all winter. The deer just about live in their yard. About 4 to 6 of them. They love apples and sugar beets.
