Does anyone have experiential proof for or against this hypothesis?
No. My chickens live in a pup-tent size chicken
tractor. It has a base that is 4'x8', two raised boxes at either end, and a perch connecting the two boxes. The 32 sq. ft. of dirt scratching space is
enough for 3 birds, and with 3 healthy birds, I can reliably get 5 eggs every 2 days in egg-laying season. They may undergo a molt in fall and quit laying for a while, but when they start up again in January or February, I am once again well supplied with eggs.
Their tractor moves all over the grassy part of the back
yard, and while they can tear up a new patch in the
course of a couple days, it grows back fairly quick. I move the tractor multiple times per day; whenever I have some
feed for them, I toss it on the ground and lift and move the tractor over it. They can't wait to jump in and scratch and see what goodies I have brought. I sometimes lift up the pup tent and let them out for supervised forage sessions, and when I want them to go back under the tent, some corn tossed inside is all the encouragement they need to return home. Mine seem to be unstressed at 10 sq. ft. per bird. I have read where 5 sq ft per bird is when the crowding stress starts to set in, so you might keep that figure in mind as you plan your setup.
