I'd imagine they would. They will eventually rot like everything else. I've eaten a few and they aren't very palateable for my liking!I have read that Acorns "turn sour" and that the deer especially like them just after they drop from the tree.
Not sure if you could tell if the acorns you buy might be not to the deer's liking.
You obviously don't have any oak trees on your property and I take it for granted that I do. Seriously, in good years we have so many acorns that the deer (or hogs) are hard to pattern. If your after hogs, corn, especially soured is hard to beat. But I guarantee that if you want to buy acorns there is someone out there that has some to sell.I recently watched a tv show about hogs and the gentleman running the place was feeding his hogs with acorns right out of a bag like corn. Does anyone know where one might obtain these acorns in bulk?
