Hello, we will have a lot of snow melt this year and the chicken runs are starting to get flooded in areas. The ground is still frozen. What should I buy to fill in the runs -- wood chips? Whatever I put in will get very wet so I am concerned about mold. A lot of the chicken run area is under the coop so access isn't the easiest for trying to re-grade (and the ground is frozen). The run areas are large. Thank you.
