Again, we don't know what we don't know, but if OP dumped clean.....but wet.....chips in the coop, they introduced a whole lot of water and moisture in there they didn't want. Frostbite city! If it is going to remain warmer in coming days, and you see the chips drying out.....leave em......toss the scratch on and let birds turn em to dry em even more. But remember, this time of year, moisture of any kind and from any source is not your friend.
Great idea, however to get rid of the droppings pile. When that thawed out, it was going to A: reek, B: release days and days of accumulated frozen water.....as much or more than anything you brought in with your wet chips.
