I've had my chickens for several runs now, and I'm trying to eliminate any potential problems. I've noticed my run getting stinkier off and on lately, and I'm hoping to find the best cure for this situation. Every so often, I've gone in there to turn the floor under, but perhaps I should do this more regularly? Also, different feedstores have recommended various stuff to sprinkly around the run to help with the smell. Three of them are Zeolite, Sweet PDZ, and of course DE. I'm trying to be as non-toxic and safe as possible with my flock, and would to unknowingly add something to their run that might be detrimental. Are there any suggestions on which of these would be best, and how to use them in my run? Thankyou so much!!
