I've posted here a few times before about his agressive behaviour. He (Henry) and my other male zebra (Chester) used to be buddies, but suddenly he turned into a little flying jerk, and they've been living in a divided cage ever since. Separating them seemed to calm things down a bit, but this past week has been very annoying.
I gave him a mirror with a little perch (about a month ago), and at first, he seemed to like it. He's been doing his very best to build a nest in front of it (out of feathers and leftover millet twigs

Has anyone had any experience like this? Do you think adding a female to the mix would set him off even more? I'm hoping I can get him to quiet down a bit, because he's driving my roommate nuts. It's getting to the point where I'm worried she's gonna ask me to get rid of him

Thanks for any and all help.
