At the very least, you could plan on having one main section right off the coop, that's covered in sand. It dries well and is easy to rake clean if you need to. This keeps you from having a wet, muddy, poopy, stinky run.
You can have other sections that you rotate the chickens into for foraging. If they are stripping them too fast, just don't let them into those sections for the entire day. It's okay to just let them forage for a few hours at the end of the day. That will keep them from destroying all the plants, while you figure out how much foraging area you need or want to provide.
I would add additional plants for food, too. A little added gardening effort can provide much more food value in the same space. A huge kale or collard plant will provide more food than a little bit of grass in the same space. They love chard, too. Plus beet or turnip tops. Grapes can grow vertically and they will eat them as they drop or jump for them, if they aren't too high. Many vegetables can be grown vertically, too. They love all kinds of berries. Legumes like alfalfa and clover will provide more protein. They wouldn't say no to some tomatoes, cherry or other types. You could block any area off that you need to, until things get established. You might even want to give them a nice leaf pile to scratch in. Mine spend hours foraging under the leaf litter along the fence lines. A board or flat rock can collect insects, worms or larva underneath it, too. They soon learn to come running when you flip it over.
Over time, I just plant a little of this and a little of that. When they really like something, I plant more of it.
