from what i've heard some do it, some don't do it. the ones that don't say it's a big no-no the ones that do have never had problems. there are stories out there about rabbits dieing from whatever the chickens were carrying in their poo. i keep my rabbits with the goats and on occassion a chicken does hop in their pen but i don't really mind. i personally wouldn't keep them together cause i've had so much trouble with my first group of rabbits. plus my chickens have a yard to eat bugs in so we can't have them slacking off.
