My husband is working on the coop and he insist on a 1/4" wire mesh for the floor with a pan underneath. Both will be able to slide out. Will the DLM work with this set up? Are the pine shavings going to fall through and not stay put? It's for a small coop, 3'x4' for 3 chickens with an attached run which he has not completed. I could put liquidambar leaves in the fall and pine needles in the summer, but meanwhile when the free, dry leaves are not available, I will have to use pine shaving. We are in the city and the chicken will free range in the early evenings and more on weekends.
