I would give it a go , 2yrs ago the local wood chip producer had a problem with wrong size chips and a massive heap that they need to move, all the local farmers bedded on wood chips that year . I started on a ft deep and had to rotavate it regularly to stop it capping , others started on a thin layer and added fresh when it got dirty both methods worked , in my case when it got dirty I just added straw ,worked ok . The only down side is that it takes a long time for the wood chips to rot down
