Thanks folks! They're so funny, they eat at the same time & he has shown her how to play so I got to see her use her toys for the first time. I love how they immediately wanted to be as close to each other as they could get. My only regret is not getting two at once.
Just a quick update, I know I only just moved their cages into the same room yesterday but I wanted to use my day off today to monitor them in the same cage in case they needed to be separated before I go back to work. I rearranged Grey's cage with thought to keeping both sides equal, I placed him in the travel carrier near Toki so they could chat while I cleaned and remodeled & now they seem to be happily cohabitating. Since they were so good I let them use some stuff I've been saving for the new cage, right now they are both perched on the wacky wood sharing some millet!
So I really wanted to thank you all for the advice & encouragement. This wouldn't have gone nearly as well without you all.
