What bush/plant would chickens like in their run?

[twinkids*tripletchicks]

I free range my 3 chickens whenever I am outside and they love to sit in planter boxes eating blueberry leaves. I would like to make planter boxes especially for them to put in their run, but I am not sure what bush/plants would be best. Thank you for any suggestions.

They will eat a wide range of plants, the problem would be that they will eat them and kill them very quickly. I have noticed that the hens at my community garden will pick the ripe blueberries and leave the unripe ones for next time. What a hoot!
