We didn't take out our hedgerows but the Chucks still dissapeared. The only places we find them are under buildings and in rock piles where the coyotes can't dig them out. Coyotes showed up here on the farm in the early 80's and the 'chucks and rabbits dissappeared fast. The rabbits have made a comeback the last couple of years but the 'chucks have not. We don't miss them in the hay fields either!
