We have a pie cherry tree that produces a LOT of cherries. I picked some off the ground and gave them to the girls. I figured they would do like the Robins and pick off the flesh from the pits. I saw at least one of them toss down the whole thing. Mind you these are not giant sweet cherries but the smaller tart pie variety, maybe 5/8" in diameter. Relatively speaking the pits seem like they might be a bit much for a chicken since I seriously doubt they will be digested and will probably have to pass the digestive system whole. What do you think do they get cherries or not. By the way, I am not about to pit cherries for the chickens. David
