Everyone has their own reasons for clipping or not. My grey was clipped when I got her and I watched her struggle for almost a year before she was fully flighted. The joy of watching her fly to me is priceless. Please read the many threads here at the forum on this subject. Some greys change when their ability to fly is taken away. I would hate for Abby to become resentful and onery because she could no longer fly. I would hate to see her spirit broken.
Ana Grey hangs upside down now and then also. I wouldn't worry about it. I believe some members have posted pictures of their greys hanging upside down. It's quite cute isn't it???
So how did the lady get him back in? It must be pretty late where you are in Michigan. Perhaps you should wait until morning to let him out. Will he step up for you? That's how I get my grey back in her cage with the step up command and then return her to the cage. In your case a fresh day might be a better time to let your grey out and then he may want to go back on his own if you two aren't use to each other yet.
Happy to hear that your travel and visit with the family is going well so far. What a great brother-in-law you have to have made Paco a stand. Enjoy your family and have a safe and happy holiday! Merry Christmas!
Congratulations on Francis coming home. I would go by Francis pace. Is he use to coming out of his cage? If so, I would open the door and see if he wants to come out. Just follow his lead. If not just sit and talk to him and offer him some treats. Watch his body language and see what pace he wants to set. Enjoy!
