Anything that produces stress on the bird tends to depress laying: heat, pecking order issues, pestering roosters, changes in the environment, etc. So if you can think of what you can control to make the hens more comfortable and happier, they ought to lay better for you.
I don't think chickens care about how clean the coop is, but I do think they care about their nests. Mites can collect and hide there, too. I use plastic nestboxes so they can be easily and frequently cleaned and the bedding replaced.
