You might want to look into 'pasture rotation' then.
I saw it somewhere in an old book: you put your coop in the center, add a run for everyday turnout. To that, you attach your roaming spaces on either side of the run.
If need be and location allows, you could then swap the run to the other...
electric fencing has other bonuses as well, like keeping things out.
I can attest to the learning curve of farm kids vs electric fencing. they learn quickly that the fence bites. Not to mention it isn't a huge shock.
