It's kind of you to feed the deer, Holly. As much as I don't like them nibbling on flower buds and some plants, I wouldn't want them to starve. I suppose there are a few twigs sticking above the snow in the woods, but like meiramalka said the snow makes it a lot harder for them. It's good to hear they can at least navigate through it.
