What we really need is modern inefficiencies built into organic methods. that needs to mean one hundred bird flocks along with a mobile coop egg laying house along with a portible fence system able to contain the flock inside an appropriate section of sod. My guess is that a thousand birds can with ten coops process twenty acres in ten weeks.
The purpose of all that is that the birds will dig up all that dirt and strip it of all plant material and all insects to depth. Significant fertilization takes place as well. In short the field is effectively sterilized in preparation for a new crop.
This integrates the hen operation into the organic soil preparation and captures most of the costs associated with soil preparation. That may well be enough to offset the increased costs of having free range birds.
Better yet, since feed stops been a significant external cost it becomes possible to breed far superior bird to produce both eggs and meat.
Thus a 640 acre farm can plausibly handle ten to even twenty thousand birds as well as ample plantings as well.

“You don’t take a five-year-old cage system and rip it out,” says Anderson. “The economics of that will put people out of business.” Instead, farmers must find ways to spread out the cost of those cages over time until they’ve gotten their money’s worth.
