Real late update. He didn't like the cage, kept crying out all night. So I moved him back to his old cage. The next day he snuck out of his cage and into the new one of his own will. However he only likes to sneak in there, not live in there. In introducing him to the new one he discovered he liked to fly to the m2's cage and display his dominance over him. He has been persistently harassing him to the point I have to lock his cage now when it's normally open (he can fly around in the bird room, but used to avoid the other birds). It is interesting since the last 20 something years he avoided our other cockatiels and cockatoos cages.
Now the m2, who is normally very docile, has been biting me ever since the Goffin started to harass him. I'm thinking of moving him to another room to get him to be nice again.
