I never had the privilege of eating a Chesnut fed squirrel. I have eaten them fed on hickory nuts, acorns, beechnuts, dogwood berries, poplar mast & I can't really recall what else. A young frying size squirrel was always high on my preference of game to eat though, so there is little doubt in my mind a Chesnut fed one would be delicious.
