That's just another snake oil 'enzyme' product....might work in a house on cat pee, but I'd never bother with it in a chicken coop or run.
Wet chicken poop in the run is gonna stink. Ridgerunner gives good advice above.
Mine stinks too after a lot of rain, but it drains well so it doesn't last long.
Best bet really is to get a lot of different sizes and kinds of organic materials out there, after correcting any drainage issues,
to help create a biological population that will 'digest' the poops...this will also provide things for your chickens to eat and they'll do there part by keeping things stirred up.
