Ok, squirrels are not chicken predators. No squirrel is a match for a grown chicken. Would they eat an egg or kill a chick? Possibly.
Lots of advice here for killing. My personal advice is that since there is ALWAYS another predator your efforts are best made toward excluding predators from your chicken housing.
