My chickens are free range, but do have a chicken house to roost or for bad weather. At this time it is only 10x8, but when we move it will be an 18x9 building. Even with the pine bedding, it still can have smell. I saw this on a website and was wondering if it would be ok to use on the bedding. It says no smell and is a probiotic base. The name is Stench Drench. This is the link to the product so you can read the info about it: http://www.drsfostersmith.com/product/prod_display.cfm?c=15498+15625+24335&pcatid=24335
It looks like that should do the trick. I'm an old farm boy and I love the smell of my coop and goat house. I change out my coop material twice and year and add periodically.
I believe it will work fine. You could always change out the bedding and clean up the coop more often. That may help also, but i think the spray would be cheaper and use a lot less energy.
