Mission accomplished! Neither bird would have anything to do with it on the first attempt. I gave them a couple days with cages close and then tried again. After 20 minutes of climbing the cage wall Jr. went into the big cage. He is getting around alright with his short wings. He climbs the walls if he ends up on the floor.
As far as interaction goes there was a lot of crazy beak kissing or beak biting with an occasional foot on the others chest. Being new to this it sometimes appeared to me as aggression with Harry cornering Jr. a lot. This was non-stop for a day and a half but they seem to be settling down a little. I'm guessing they are establishing the pecking order with a lot of pecking. No squawking. Just a lot of warbles will chewing the other's beak.
