@flocking-crazy: I'm using aspen chips for inside the coop. For the chicken run, I have small rocks. To more easily clean the chicken coop, the bottom pulls out. Like a drawer. Let's hope it works as planned.
I used 2x4 for the foundation. I used ply wood for the sub floor.
I had 3/4 ply from a previous project that I used for the walls that go up against the fence.
I made a skeleton of my exterior walls, framed out windows and door opening.
Roosting boxes are 1/2 ply.
I used left over 1/2inch...
