My general feeling these days it to keep large populations (of roosters as well as hens), starting with many breeds, and allow them to mix themselves randomly. And constantly be bringing new blood into the flock. Then allow a combination of natural and human selection to tailor the flock to local conditions.
If three farms are keeping a population of chickens like this, then spiral breeding is a great strategy, (move the new roosters to the next flock in the rotation). But the fussy record keeping required for a spiral breeding project on one farm seems too hard.
