To OP Brian, I'm curious about the origins of that fence. What prompted the necessity of razor wire? And how big of an area is enclosed within this fence? What is the spacing of the fig trees? How many trees?
Is the fence on the property line? Either way, you can enhance even that by the addition of electric fence wires at the base and at the top......basic livestock type E fence. That way not much is going to dig under or crawl over it.
Combine that with an open air coop (wide open air) with an electric door, and you will have done about all you can, given the situation you are trying to adapt to. You may get losses but that seems to be an occupational hazard for these birds.
Normal laying hens may not be the best choice. Perhaps guinneas?
Perhaps you could get some mail order feral chickens sent to you from Key West, FL? They somehow manage to stay alive roosting in the trees. (kidding)
