I have been a lurker for awhile and we just built our first coop. We have very little real building experience, this is by far the biggest project we have ever built ourselves.
Plan is for an 8' x 16' coop
Breaking ground. Treated 4x6's on cinder blocks. We picked this spot because of the good tree cover. We have lots of birds of prey in the area.
Next we had to level all the 4x6's. This took the most time of all the project
Next we built the floor frame out of 2x6's and squared it up. This rest on the treated 4x6"s and does not touch the ground.
Next we installed a subfloor and started framing our door. I used instructables.com to learn basic framing. We used AdvancedTec sub flooring and green lumber for the framing. All the lumber we used from this point was green and from a local sawmill.
