Can you build deep litter in a closed, raised, wooden floor coop?
I'm doing deep litter in their dirt floor run that's open air surrounded by hardware cloth and partially covered.
I don't see how deep litter can work in an enclosed area that gets no rain or has no drainage.
here's a pic of my coop and run. The area on the right is deep litter and the wooden house/coop is Sweet PDZ.

My coop is closed with a wooden floor and deep litter does great. I have a tarp over the floor to protect it and have put pine shavings and leaves over that. The chicken poo provides the moisture but I'll admit that I also add some dirt from our woods to the mix. The dirt inoculates the litter with those leaf, litter, and poo eating critters and enzymes to help it break down. Plus, the dirt has a bit of moisture in it.
My profile pic is of my coop and - like you - I've got several windows that allows in a bit of moisture from the air. If your litter gets too dry, you can always spray it a bit with water.
