most folks will say no, but I've seen pics of folks who do. Just have to have a place for the rabbits to have a feces free area for food and water.
There are people who do it. I personally keep my rabbits in their own pens because I don't want them running around in all that chicken poop and getting it all over their paws. Also have to consider if the rabbits will be able to dig out of your chicken pen or if you have any aggressive hens or roo's who will not appreciate them. Rabbit's eyes are vulnerable to well placed pecks. Rabbit's like to be active at night which chickens may not appreciate. So, all things considered I just keep mine separate.
It works for me. I have a 10x20 run surrounding our coop and our rabbit has full access to it all. It's really really dry here, so I don't have a problem with poop..it dries up and blows away in just an hour or two (it hasn't rained since OCTOBER of last year ) . He has his own little feeder and waterer, but they all sample each other's feed. I only feed flock raiser, which is vegetarian/plant based, so it doesn't hurt him if he steals a little. But he prefers his own feed, which my chickens love to sample his pellets too. They all love it if I throw a few flakes of grass hay or alfalfa on the ground. I do it rarely (like 1x per month), but it's a big treat for the chickens to dig through and for him to munch on. He does like to stir it up with the chickens. He loves to aggravate them, which is pretty funny. Nothing mean or potentially harmful, just playing. He will run circles around them and dart through their legs in the evenings when he is just waking up and feeling fresh. He mainly sleeps all day. When it was bitter cold this winter he would hang out in the coop with them where it was warm, they don't pick on him, everyone gets along well. He does dig some holes, but the chickens love to stir up the dirt in his holes for their dust baths. He can't dig out (well I guess he could, but he doesn't have the ambition, haha), I have wire buried along the walls of the run. The chickens go up on the roost at night. He doesn't bother them at all, he can't reach them They've lived like this for nearly 2 years, no problems at all....for us, anyway! ETA: I do NOT have a rooster....I might not recommend housing them with a rooster.
