finch - irritating little brat to canary?

[delsolarie]

Hi all, we have a large indoor aviary (15x12' & 10' high). Before we built the aviary I had my female zebra finch (Tikay) and my female canary (Shiloh) together in a cage. They were great buddies. However - now in the aviary among other birds I have added another female canary, a male canary, a male zebra finch who can't fly and another zebra finch (I don't know if it's a male or female because it's a pied with a red beak but no cheek patches??)

My problem: The male canary (Pharoh) is very interested in Shiloh. Shiloh has been trying to build a nest and flirt with Pharoh. However, Tikay isn't having any of that. Tikay will follow Shiloh around and sit in between her and Pharoh. If Shiloh puts some material somewhere in attempts to build a nest, Tikay will just grab that material and throw it off!!! Is there anything I can do aside from removing Tikay from the picture (which I do not want to do)?

Please help!!
