I find the deer will eat the apples first, then corn second, and only start eating the carrots when not much else is left. I live not to far from a carrot factory i guess you can call it lol, and they will sell you a trailer of funky shaped carrots for around $10. So we filled out trailer full to the top and dumped piles of it everywhere and them spread the rest all over the pasture, and the deer only started eating it after it had snowed and other food was harder to get at. Now we stick to apples and corn.
