Lots of great ideas! Never even thought of a fencing contractor. Figured the job would be too small, and they'd charge too much. The guy that came out is a handyman and does lots of other stuff besides chicken coops/runs. I will ask for his email addy so he can email me pics. Good idea! I won't put anything on top of the apron--makes sense. Never even dawned on me to call high schools or colleges either!
And yes, I did think about the chickens trying get a weed or something outside the run and sticking that head out (Oh, the horror of the thought of that!) So I'll do the wire two feet up, and then two feet for the skirt as recommended. Now I'll just wait for him to call back, and if the estimate is too high, I'll wait until after the holidays. Too much all at once!
