Don't worry too much, the ones round here like my pheasant feeders!!
If anyone is feeding big bales of hay outside, and the deer are hungry, you soon get a visit. I know people who use kibbled maize and others who use carrots and one who buys up the stuff thats looking tatty from the local greengrocer. I think familiarity with the food source is, as previously stated, essential. Like putting out salt licks, it takes them a while to get used to them and to try it. We used apple pulp one year, and nothing touched it, they still keep hitting the feeders though!!
