Hopefully you have a place to store the pile of wood chippings.I have signed up for chip drop but wasn’t sure about how long I would need to let the chips dry out.
Let it sit for a week or two then scrape the outer layer off the pile and spread it thinly in the run to dry further, do this every week or two until you get a couple few inches of chips in the run..
Have you tried local tree trimming services?
They may be able to respond more quickly.
