Would anyone know of any books on designing a chicken friendly garden? We have not long come out of a very dry Winter and there has been little rain so far this Spring -- Summer is not looking terribly good either. With a lack of rain, the grass has died with no sign of returning, particularly in the area where my chickens are kept. Aside from kitchen scraps, I've had to resort to feeding them a lot more seed. It may take some time, though I would really like to provide a sustainable garden with plenty of edible plants and herbs for the chickens. Book recommendations or general advice would be greatly appreciated.
