parrot finches question

[Mattyboy]

Gouldian hybrids are very rare, I think you'd probably have to try very hard to make it happen for it to eventuate.
The only potential problem you may have, is that both the Gouldians and the parrotfinches are hollow nesters, so they may compete for boxes or logs.
Canaries are notorious vectors of airsac mites so that's a potential worry as well.

only thing I found when I had parrots was that I had to increase the number of nests available for the birds to choose from. instead of allowing 2 nests per pair in the aviary I was having 4 or 5 nests

Hmmmm that nesting box scenario could quickly clutter an aviary. Might wait until I have another aviary.
