22LR works fine (Ruger 10/22) on coyotes with good placement in the kill zone (not head), but our chickens were done in by mink. Chickens are stupid filthy animals anyway. Get our eggs from a neighbor who keeps them in a varmint-proof cage. Eggs are cheep. Practice with a 22LR (which is cheep to shoot) and your range will improve. Get some advice from a competitive shooter and it will go a long way in improving accuracy.
