Now, forgive me if this looks crude.  The picture you are about to see represents 15 minutes worth of thought and actual work.  I needed a quick solution to hanging the nest boxes so I could continue moving the chicken tractor.  Three and a half 2x4s later…

The boxes are hanging from screws in the upper 2×4.  There are tarp straps holding the bases together so they don’t swing in the wind.  Everything seems to work fine but it’s suddenly quite a heavy chicken tractor.

I put part of an old tarp between the two nest boxes hoping to offer the hens a little privacy without adding much weight.

So, there you go.  There’s still room for feed and water in the shelter and there’s plenty of airflow.  I just need to make it a bit lighter.  Let me know if you have any ideas.
