I have. It's a nightmare, they're after grubs under the grass...leatherjackets or chaffer grubs. My lawn at work looks like a bomb site.

I just fill with soil and put a bit of seed down. you shouldn't have to cover with chicken wire as they won't be digging in the same place twice once the grub has been dug up.

In both cases (snoop and Kornos) I'd be treating the lawn for leatherjackets - you can now buy a nematode treatment for these, but you probably need to order it on line, and these treatments are only effective when the soil is at a certain temperature, that is, not cold like now. Nemesys is the company which makes it - otherwise,I think Provado does a lawn drench treatment which should kill them off. After treatment, that's the time to repair the lawn...

Also sprinkle some urine around the garden, this should deter them but you have to keep spreading it! I have heard bunches of human hair does the trick too.
