permaculture

Help! I have over an acre of land fenced in. The problem is that I have had a pair of roadrunners living on the inside of the fence. They were here before I moved to the property 15 years ago. They are experts at cultivation.  I expected to feed birds and rabbits but these guys are to smart and able to get into anything but garden fencing (anything under 3 feet easy) . Does anyone have ideas, prior experience

I think they eat a lot of grasshoppers, if that's any help....

Roadrunners are like chickens, best kept out of vegetable gardens because of their scratching habits.

You can use bird netting that is well fastened down at the bottom edge, tall fencing will help but they do fly so really the netting is a best bet solution.
