I've had sand in my run for the past five years, and for the most part, it has worked out great. However, the run is covered and I erect green house panels on the sides during winter, and the environment is exceedingly dusty. I was giving serious thought to getting rid of the sand and using wood shavings.
Then I got to thinking about how easy it is to keep the poop picked up, and it might not be that easy with shavings. Also it might invite insects to take up residence. And the chickens wouldn't be able to dirt bathe whenever they felt the urge.
It's dusty because the ground under the sand is clay soil, and early on, I mixed decomposed sandstone with the sand to stretch the budget. This summer the flies began to hover over the sand since we've had a wetter than usual summer here in Colorado. So I did a couple of applications of Sweet PDZ, which discouraged the flies, but now the sand in the run is dustier than ever.
I went so far as to purchase a product called Dust Locker to quell the dust. But I fear what might happen if the chickens ingest sand particles that have been treated with it. I don't know what effect it might have in their crops, even though the product representative assured me it was safe for chickens.
Has anyone used this product around chickens or something similar or know anyone who has? I love the sand in the run except for the dust problem.
