Try to keep them away from strange chickens to lessen the chance of an infestation. Check them regularly and treat if you see an infestation. Checking them from the roost at night is usually a good time, they are easier to catch that way.
I've gone over over ten years without any mites or lice, some of that is luck. As Sour said, wild birds can spread them but it's not a given.
