Knowing now that you aren't going to entice chickens to stay at home unless you fence them in, (preferably a covered run like a tractor), I'll answer your original question about what plants chickens like that are likely to survive their activity.
Most sod grasses are very vulnerable because the roots are shallow and the chickens' scratching uproots and eventually kills the lawn. It take a few years to get established, but the best grass seed to plant with chickens in mind is native bunch grass species. This grass grows in bunches, not a mat, and it's a perennial so the root systems eventually grow very deep, making it very hard for chickens to dig up. Chickens need good grasses to eat.
Likewise, shrubbery with edible berries would be a good choice since large shrubs are deeply rooted and will resist chickens digging them up. As you add more plants for the benefit of your chickens, make sure to choose things with deep roots, non toxic leaves and berries and flowers, and protect them from the chickens until the plants are well established.
