Hens and rabbit

i think it really depends on how big the space is and how many rabbits/hens there are within the space.

We have ours together, we have 8 chickens and 4 rabbits that live happily together. The rabbits always end up in the chicken coops and the chicks like to sleep downstairs in the rabbit hutch when they get tired during the day.
They do have a lot of room though inside an electric fence enclosure so they can stay away from each other if they want to.
You'll find the ground will get dug up more as they turn it into a team effort, the bunnies start the digging then the chickens carry it on to make themselves dustbaths.
So if you have enough room for them to stay away from each other if they want to then should be okay =)

My chooks and boys get along just fine.

The only problem I have is when I open the shed door in the morning to let the girls out the bunnies try to sneak outside amongst the chickens. They not hard to spot, I just have to be quick, as the boys are pretty new and have yet to learn to come when called. (This works just fine with the cat as long as I remember to only call her when she wants to come.)
