Describe in detail if you can your ventilation.6 birds but looking to get more and about 10 to 12 feet of ventilation. I just didn't know if there was a bedding that helps with the odor. I am wanting to get away from straw.
I also have in excess of 1 square foot of ventilation per bird.
Personally, I use ~ 4-6 inches of pine shavings.
I gets refreshed when needed, but only replaced about once per year.
My coop is dry and odor free.
