I am so floored at this idea. My fiance and I are still in the way early stages of planning for chickens, hopefully by next spring. I've been going over and over and over different websites, looking for the cleanest most cost effective way. I had been leaning towards the rotation idea where you put the cleanest bedding in the nesting boxes first and then rotated outward until it makes it to your compost bin. But I am SO Glad I ran into this thread before I purchased a coop. I could only make it to page 22 before I realized it would take me days to absorb all of the information here. I'm not sure if any stores around me carry PDZ but I did some searching and it's available fairly cheaply through Amazon. And with the length of time it seems to last, I think it's feasible and probably more cost-effective to go the online route. We are planning on only having a FEW chickens in the 3-5 range since we do not have the property or yard space to incorporate a huge chicken coop. I'm happy to go with something small but it seems like most people here have some gigantic flocks. I'm worried about the smells offending my neighbors coming from a coop with only a couple chickens, I can't imagine what it must be like with 40 or 50. But I think if this PDZ stuff can make a coop that large stay fresh, it can probably handle just a couple chickens. I am so nervous and scared about upsetting the neighbors, and I want to be as considerate as possible. But thanks to this thread I think I have the answer to the coop! I know I haven't read the thread entirely yet so this may have been answered already, but does anyone use this for chicks too? Also, I'd be super grateful if anyone can point me in a direction towards finding out about keeping the chicken run clean and the smell down. I see a ton of information about coops, and not so much about the run.
