Just adding some input; I got a rabbit and it lives separately from the chickens, but outside still. When I am home I let it in the chicken run and they get along fine. They aren't by any means 'friends', but they don't mind each other. I think it is a "you leave me alone I leave you alone" arrangement; like bees. I live near San Francisco in a SUPER hot part of California (last summer we had some 115 days, but our summer average is about 105) so if you live somewhere like me don't let it out to run with the chickens during the summer (bring it inside) because it will over heat VERY fast, especially if it is running/hopping. Just because your chickens are fine to be outside in that weather if you just spray them with the hose dose NOT mean your rabbit will. That's the only health problem that I've run into so far with it (it was 99 degrees yesterday and the summer has barley started [*groan*]). So I would say part-time rabbit and chicken co-existence is fine.
