Take a closer think about that supposed bed rotation "moving every
two weeks around 6 beds". That means that each bed is hen-dug every 12
weeks throughout the year and by implication is, it's also re-planted
and harvested every 12 weeks throughout the year. Is that feasible in
your climate?

This sounds very like the system proposed by Linda Woodward(?surname) in
_Permaculture Home Garden_. In this case, IIRC, there were 12 revolving
beds in a mandela, and the chooks were moved each two weeks, allowing
one month for each bed between chook visitation. The chooks would only
go around the system for 6 months of the year and would then go off
either to another mandela of garden beds or to a safe spot under a fruit
tree to allow the garden beds to rest.

The idea was for there to be quite a bit of greenery and such remaining
for the chooks to eat - in fact any empty spaces in garden beds were to
be sown with mustard and similar as extra nutrition for the chooks. The
system involved a bit of waste but was desgined to catch pests before
they became a problem. Of course, your point about speed of growth is
stil valid Janet - the system was designed for a wettish, subtropical
climate.
