Keep in mind that people have also different sensitivities to smells, especially if you're new to chicken keeping.
I use PDZ and sand on my roost boards and sift the solids off them every other day or so, adding a bit once in while...yep, it kinda stinks, but not an overwhelming ammonia stink as the PDZ neutralizes the ammonia and helps dry out the poops. I use pine shavings on the floor, along with PDZ that gets kicked off the boards, and stir those up when I sift the boards and add some extra every once in while. I will totally change out the shavings twice a year. Nothing covers up a fresh cecal poop stink, but the PDZ will dry those out too. I also have lots of ventilation.
I used to chicken sit for a guy who used no bedding in the coop, just 2-3 inches of dried poop that he scraped out maybe once a year....that place would make your eyes water and forget about breathing thru your nose in there.
