That is why I like bantum chickens. They don't dig as furiously as larger breeds most of the time. Note I said most of the time. Mine have access to the compost pile which is really an old hay ring as well as being free range some of the time. I use to volunteer at a botanical garden and got to bring home plants, plant trimmings, 'spent' potting soil, etc. I would put that under my rabbit cages and the chicken would mix everything together for 'black gold' in just a couple or 3 weeks.
