My chickens free range in larger and larger circles the older they get. When I used to keep 18 birds in a 50'x40' area most of the day, they ate everything until it was just dirt. My 'lawn' is sticker burrs, weeds, and dry grass though. Once I started letting them out more the grass grew back better than before, and actually they got rid of all the sticker burrs! My chickens have a designated dust pile bathing area, but still choose to take baths in whatever random sunny spots they feel like, leaving chicken-shaped craters everywhere.
I'm not sure what would cause your birds to be more destructive than usual.
I agree with other people on here, one solution would be to cut them off from parts of your lawn. You could switch back and forth so that when their area gets a little barren, you move them into the grassier area. The poop is great for your lawn long term.
