Different places, different deer... I've put out trace mineral blocks several times over the yrs and nothing has eaten them. Rats and stuff don't even mess with them, they just set there and kind of dissolve over a long period of time. I've even poured corn over a block to see if I could get them started but they had no interest once the yellow was cleaned up. I've had some success with granular minerals and water softener pellets. They seem to like that combination, but being salt heavy it probably just tastes good...
