Bonding Trouble

I have a neutered male rabbit named Kovu and he's been with me for about 4-5 weeks. I was worried that my other neutered rabbit Cutie would be the one that would fight with him but instead it's my unspayed female rabbit Coco that is fighting with him. She is a Flemish Giant/Dutch cross and he's just a little lionhead! They all share a big pen and Kovu runs around the pen and Coco turns around and tries to bite him but he just hops right over her.:shock: I'm really worried because Kovu is so much smaller than her! I've never had any trouble before bonding my rabbits so I'm not sure what to do. Any help is greatly appreciated!

Unspayed females can be really moody etc. It would also depend on her age etc but sounds like her hormones making her a moody bun!! If she was to be spayed she would prob be much friendlier towards him

Thanks! Oh and by the way she's 5 years old.
