Thanks for the information!

Actually, the dominant pair is a male zebra and a female society! (When I got them, they were already paired like that, it wasn't my idea! ) The female society basically just sits there, she is not aggressive, but the male zebra chases all the others away from her and the center of the cage. So, this one pair occupies 2/3 of the cage, right in the middle, and the other two pairs of white zebras have to sit on the edges.

None of them have nests. I don't need anymore birds! Although they all still lay eggs constantly on the bottom of the cage. Gggrrrr.....

I actually had four pairs in this cage, and I took the dominant pair (both dark zebras) out and gave them to my friend. As soon as they were out - and I mean like within 15 minutes! - this other male took over the dominant role, and the same nasty behavior. I was soooo frustrated.

Could I just leave the situation as it is? Will they ever do damage to each other? Right now, its just chasing and squeaking, basically. I'm afraid if I take this pair out, which I really don't want to do, the next male in the hierarchy will take over! I don't want to just have one pair of whites in there, eventually!

I swear, these birds are as bad as my dogs with their pack-order problems!
