I read somewhere, can't remember where, that some people use a thick layer of dried oak leaves. Would they dry quick enough? Especially if they were on top of the slats? I hadn't really worried yet because they are in the yard from the time I wake up to when they go to bed; scratching and eating, under the deck taking a dust bath, or on the deck looking in the house and knocking on the door with their breaks. There's no mud under the hen houses so I wasn't going to put wood there. Would the leaves work do you think? I'm broke and have 11 access total but other than yard, I'm completely surrounded by hardwood. The street I live on is White Oak Drive.
