I am a newbee and wanted to share and show off the coop that I had built!  I am quite proud of it!
I had incorporated my chicken coop (about ~4' x ~13') under my shed that I had built last year.  Maximizing the space, I positioned the shed at the edge of my level yard, to where I have a slopped wooded area where there is no lawn.  I also utilized the space below to include a 16'x16' run for my 10 hens.  I made 3 nesting boxes out of a pallet that I have at the bottom of the stairs, making it an easy go-and-grab for the eggs.
This is my first year raising chickens but they seem pretty happy!  They've been delivering eggs regularly to me for the past 1-3/4 months.  I also began letting them roam the wooded area, clearing out the overgrown stuff.  Of course, I only do this when I am working nearby so that I can keep an eye on them from the predators.
