Linda,
I know there is a lot of controversy surrounding wing clipping. However, the behavior you describe sounds like you are having dominance issues. Rosies are known for being easy to tame. Obviously this is not always the case. If it were me, I would clip their wings. If you've never done this before you would want to take your birds to someone who has. Then I would initially work with a washcloth to avoid the worst of the biting (never use gloves) and handle them each day. Just be very gentle and talk to them in a soothing voice. I believe this could change their behavior. AND if for some reason it doesn't work out, you simply let their flight feathers grow back and you're back where you've started.
