how do i stop the bird or squirrels kicking my chipwood all over the grass

its probably birds turning over the woodchips looking for food. This happens a lot, i dont how to stop it though but they are removing pests all the time.

Yes like sbg I know they look a little unsightly, but think of the good work they are doing ridding you of bugs! I go around with a sweeping brush now and again and once they have worked it over they settle a bit and the problem becomes a little less. Its a little price to pay for the less weeding you have to do and the goodness to the soil when they break down.

Chickens do the same! I have made little (6 inch) woven 'fences' from Cornus prunings. Any straight woody shoots would do, or buy some willow for weaving. Push stout sticks into the ground every 6 inches and then start to weave the long thin shoots in and out. This stops the chippings (or gravel) from going all over the lawn or path.

yes a small surround would keep them in somethink like a edging strip?

in short , you can't.
it's what birds do, you could try putting in some lawn edging that was higher than the chippings, but blackbirds can throw this stuff quite a way!!
just treat it as good excercise :-) .....steve
