They'll eat most any condition, fermenting apples as well. They especially love the pomace (pronounced same as "pumice"), the somewhat dried fibrous residue leftover from making cider; the local hunters flock to the orchard to get pickup loads of the stuff for bait. Not legal, but - we all know plenty of "hunters" that don't have much regard for laws. And Rico is right on the money - I've seen them at the pomace piles in the winter at the orchards, some will not touch an apple in the pile (the apples not fit for cider-making are sorted out and tossed into the pile) while others root through the pile like pigs trying to find the apples.
