Other animals in chicken area?

[Chickaroos]

I finally finished my HUGE chicken area in the yard. Im not sure off hand exactly how big it is, but its super over sized for only 12 chickens! Just curious what other animals can be kept in the same area as chickens? I was thinking rabbits, but my fencing is not deep enough for their digging. Any other ideas?
