Good luck Alice and keep us posted. I have a quaker parrot, a CAG, and a recently rehomed Panama Amazon. They are all out at the same time. I keep an eye on them, but for the most part they behave themselves. The CAG and the quaker squabble occasionally, well actually, the quaker picks fights, but my CAG is so mellow he doesn't fight back, or if he does, he is no match for the speed of the quaker. I have had the quaker and the CAG together for three years and there have been no injuries, just posturing, and minor squabbles. Quakers have no concept of their small size.
