I know nothing about housing different species of birds together..

But I did want to add that Joey is absolutely stunning.
I love his colors, and his white face, with the grey around his eyes..

I'm in the process of convincing my other half that I need a bird (a green cheek conure).. It's not going over well, but we have a lot going on right now, so I probably won't.
Please post more pictures of your handsome boy so I can drool over him instead.
