Are you just using it on your grass? You need to get to the root of why you have odors and where they are.
We used this Sweet PDZ in our brooder because it helps the poop & shavings compost a bit faster, and then you can just dump it into your compost bin when you are cleaning it out.
Sand also seems to be the newest trend in keeping things tidy, you can use it in your coop and just scoop out the poop a couple times a week if you only have a few birds.
If free range bird poop is making your whole yard stink, you have a problem. I would look into their food, and figure out what is going in the front end that is making the end product so terrible. Too many treats/scratch? Too much people food? Are they eating something out of your yard that is making their poo stink?
All of our birds free range, and we even had 100 cornish X free ranging very close to our house and it never stunk. Not in the yard at least (The brooder for 3 weeks is usually our problem, but the Sweet PDZ for composting realllllly helps! We also deep bed, and stir it every day)
