Deer are like pigs, they will eat almost anything.
Potato chips, corn ships, cheeto's, bread, pop corn, carmel corn. You name and deer will eat it.
Need to add that they like cigarettes also. A friend of mine had a pet deer that was on the wrong side of a busy road. He owned a gun shop and couldn't go get it so he handed me two cigarettes and asked me to coax his deer back across the road. I went to the location, called out for the deer holding a cigarette, he ran to me, he ate the smoke and then I used the second one to lure him across the roadway.
This was probably 30 years ago.
