I have one guy, a mini Rex, that has two 4-month-old Serama roommates. He was suppose to be someones breeder but then came home and the chicks had moved in already, so he had to go in there with them.
They get along and he never tries to eat them or chase them. They all sleep together and its really cute, but he does every once in a while try to nibble the pullet's tail feathers while they are laying together in the evenings. Only hers for some reason... he just nibbles a sec and she makes a disgruntled noise and she stops.
They are in a huge hutch with plenty of room, and the Seramas are very small. The rabbit does eat a little (of what he can reach) of the grower crumbles, but even the little rabbit pellets are too big for the Serama.
Id say that this is a rare arrangement, I was only going to do it for a night, but the birds came off the roost to sleep with him, it was too cute and he is VERY tolerant and tame by nature.
I have two other rabbits I let exercise in the barn and run some evenings and they chase the chickens and hop around and chew on everything. I wouldn't let them stay in there.....
