Soil floor. Same thing as the garden, without the wind and rain degradation of the topsoil. Here's a pic of my coop and you can clearly see the sides are no more than 4 in. deep and that coop has absorbed about 6 bales of pine shavings, one of cedar, and 4 trash cans of compressed leaves, with countless piles of leaves raked directly into the coop itself, as well as hay, weeds, yard debris...since last year around Sept. In addition, this year alone I've already raked 3 huge piles of leaves into the coop again and they will soon disappear as well. I've got 4 large trash cans of compressed leaves to use this winter as well and am raking leaves to store right next to the coop also, as the four cans of leaves I used last year didn't last me all winter. The leaves are the quickest to just break down and disappear. I'll be raking about 3 more huge piles into this coop again next week to try and pack all the leaves I possibly can in the coop before the snows fall.

Below is just one set of weeds that has been deposited here...any that I trim off gets placed here and incorporated into the bedding...there to disappear.

The grass around this coop has greened up where the nutrients leach out of the coop when it rains but there are no direct washings of water through the coop as no water runs into it, even in a hard rain.

If you just scrape back the top of the litter you can see the moisture below it and below that is loose, dark soil.

It would have to be seen to be believed, but it's happening so well that I never have to do anything to this coop but just keep adding materials. In my coop with a wooden floor I didn't have this level of break down but I should have used some soil to culture it first and also should have stopped working it up and airing out the bottom layers..should have just let it sit and stew like I do now and it, too, would have degraded more quickly.
