Thanks for posting. I wanted to use it because we are secret urban backyard chicken keepers and want to keep any hint of odor at bay. I'll be a neat freak about their coop!
I agree, I would not take it out. I think it may help keep the odor down, but chicken poop can get stinky, especially in wet weather. Having a dry/covered run will also be helpful. Periodically add some dry leaves, pine needles, etc. to your run.
Keeping odors at bay in an urban setting may help your neighbors not detect the chickens, but once they start laying, singing their egg song and making chicken noises, your nearest neighbors may get a clue
PDZ is great in the coop on poop boards and in poop catchers - it absorbs smells and makes it easy to scoop out the poop in a couple of minutes.
I hope all goes well for you.
