Something is amiss.
I have 25 birds in a 10' by 16' coop, use drop boards with PDZ, deep bedding of pine shavings with some straw (6-8" deep, DLM is something else entirely and generally does not work on a wood floor). I clean the boards each morning. I went for over a year without changing the bedding and no smell whatsoever. I changed the bedding for two reasons: buildup of "dust" (actually droppings that break down) and I was dealing with mites. My coop is a Woods KD style with excellent ventilation.
Is the bedding damp or wet?
