I seem to recall an article on the mobile coop in the old Mother Earth News decades ago...got to see one 'in action' on a big farm I appraised recently. The mobile pen wasn't fancy, but it seemed to work quite well - though this area doesn't have nearly the number of predators Garrett has in the piedmont. This looked like welded wire on conduit....
I figured that, well, chicken being chickens, some might get run over by the trailing edge when it came time to move the contraption. Maybe the tenant farmer didn't move it all too frequently (the chickens had scratched almost to dirt....), but when he did move it, the hens would all line up at the leading edge like it was race-day and the checkered flag was about to drop. Then there was a mad dash to get to the new 'good stuff'....
You could tell where the pen was before: there was a checkerboard pattern that was *way* greener....
