I haven't had a Quaker either. I have the opinion that any new bird needs a day or so, maybe more, to adjust to strange faces, strange voices and weird looking rooms.
You will be able to tell if he is calm or needs a couple of days to adjust. Talk to him in a low voice and try not to stare at him.
My ekkie was an exception. She was a snuggler from the moment I picked her up at the breeder's. My grey was a whole nuther type. He was terrified of me and the new surroundings. It took months to calm him down so I could pick him up without him panicking.
Be aware that weaned babies sometimes revert back to needing a handfeeding, or several. Ask the breeder to give you the name of the dry mix she uses and instructions on how to mix it. Some will give you a sample if you ask. I have gotten a sample from every breeder I have used. I ask.
Good luck.
I am anxious to see the pics. I love the look of Quakers.
