I've NEVAH cleaned a run. Some folks take a tiller to them if they get compacted. Mine is a bit compacted around the new coop. That's because the new coop was built on heavy clay subsoil that never got raked/de-rocked enough, or had enough time last fall to get seeded to grass (We didn't get the coop finished until late November). So 1/2 of the run is nasty clay subsoil, that is getting reconditioned by adding all the compostables I can get my hands on. (the other half is weed/grass quite lush and healthy looking) We have a bagger on the lawn tractor, and that stuff is gold IMO. It goes where ever most needed. (on potatoes, in green house, in chicken run or chicken coop.)
If your litter is composted in the coop, be sure to leave a good base. Are your coops bare ground? Bee Kissed uses DL in bare ground coop, and NEVER takes any litter out unless she is harvesting it for the garden. She never has flies or odor in the coop. But, she free ranges exclusively, so doesn't have bare ground run issues to fix.
Yes. That stuff would be gold in the run. PDZ is Zeolite. It binds nitrogen (thus no ammonia smell in the coop) and slowly releases it. I've never used it, but IMO, think it would be fun to try in a heavy nitrogen based compost situation. The more organics you can get in your run, the healthier your run will be (unless you already have a healthy crop of grass/weeds). I'd be happy to have a 6" layer. If I had a 6" base in my run, the next thing I'd do would be to collect an army of earth worms and introduce them at night or in rainy weather. (so they can get some good soil penetration before the chickens find them in the morning.)
I got it... Reminds me of the dyslexic agnostic. He never did figure out if there really was a Dog.![]()
Yep. Get that bare gound covered!!!
Dyslexic agnostic... funny stuff!

I'm glad for all this talk about all this, because I'm starting to need a better solution, so this is all good info for me. My grounds are bare now.
I use straw in my coop, shake some PDZ first. Flies and smell are minimal. But when I clean it out, I've been tossing it over the fence! I should throw it out in the run?
Also with the new run I'm building, we are planning a run within run. Keep them in the inner run and free-ranging during winter and early spring, but out of the outer run. Then when its time to keep them penned up (to keep my LO eggs pure), they will have the new growth to forage on. I've got so much to learn about this stuff....
