There are many on here that know much more than me, but I am willing to share my experience. There is deep bedding and deep liter. Deep bedding means just what it sounds like - deep bedding. Deep liter means you start somewhat shallow and add regularly to the bedding. This is what I am doing. I started with a dirt run, added some dirt and wood chips (well dried - a forum member added fresh and his chickens died) and have since been adding grass clippings, leaves, garden waste etc to build up the bedding. I turn it over occasionally just to get the poop off the top - especially when I'm not adding anything. I've learned I don't really like wood chips mixed in - they don't seem to be breaking down like I want. I have no smell in my run. There is a video I watched that was created by one of the forum members that explained it so well, but I cannot remember where I found it. I think of it as trying to recreate a forest floor. I don't scoop poop, I don't pick up poop, I don't smell poop. I just turn it under occasionally or cover it up with another layer. Come spring the bottom will be black gold for the garden
