My Three Chicks
Crowing
I have 4 7-month old hens that I adore. They have a 9'×24' secure run which they seem to be very happy in. But I have started giving then full access to the backyard a couple of hours a day when I can supervise them. It's not a huge yard maybe 7x the size of their run but it's got grass, lots of planters, garden, patio, dirt, bugs/grubbies, garden, etc. They love it. And today discovered my herb garden. They are scratching and pecking as they do and are making a bit of a mess (kicking mulch and dirt out of garden bed, eating/ruining grass, etc) and destroying some of my plants.

If I plant a new tree, my chickens like scratching around the tree rings. Sometimes they'll dig alittle deeper than I want and when they're done I just go fix it. I tried planting them a forage area out by the barn. I can fence it off to keep the chickens out until it grows, but once again, the gophers showup and destroy it.

But as to your problem, I think I would try and pick an area, fence it off from where you don't want them to go and plant them a forage area. I think most Feed Stores and stores like
At night my chickens are locked in their coops and my rottie has access to entire yard - (except for the front of the house) and he keeps any and all intruders away. In the winter time, my rottie is usually in the house at night, but again, my flock is locked in their coop at night and safe from any harm.
