We all get wet litter in the run from time to time with the weather, and most of us live where it has time to dry out, mostly on the top. Not sure how it goes in extremely wet climates. In the coop though where there isn't as much ventilation as outside, try and keep it dryer on top. If it gets really wet in the coop then move it around with a rake to avoid soaked areas. It will moisten the coop bedding. Usually the birds will dig through after you have moved it around to find tidbits. Then it will dry out on the top eventually. Hope that helps.
