You're already well versed in the joys of owning a parrot and I'm sure she'll fit in nicely with your fam. Greys are a little different because they need grey specific food. I give mine pretty bird pellets/nuggets for african greys. They do make a natural one but she likes the fruit flavored one. Ummm...I'm thinking here. Well IDK what else to say I'm sure people will fill you in further but I want to add three things that my Gonzo would be lost without:
1. Her kabob. She shreds through one about every two weeks. likes the original and hangs upside down to it and talks to it while attacking it simultaneously.
Bird Toys: Bird Kabob all natural yucca bird toys at Drs. Foster and Smith
2. FORAGING TOYS!!! She loves this one:
Can O' Nuts and Treasure Chest Bulletproof Treat Toys
3. Foot toys. Get a variety and the cheaper the better. I get dozens of chinese finger traps, soft plastic kids toys (i.e. little rubber duckies, little koosh looking things), q-tips tied together with twine, whiffle balls stuffed with shredded paper. All these things will help build foot-eye coordination and keep your girl from being bored.
In my opinion the worst thing for a grey is BOREDOM. Whether you choose to let her be your bonded shoulder bird or you want her to play on her own just try to keep it fresh and new. One last tip- we rotate her toys every week and change around her cage setup too as far as the shape of her boing and the placement of her perches. I may be fooling myself with this but I think it has helped my grey be open to new things and not be so afraid of change or new toys like some greys can be.
Good luck, I'm sure you'll get lots of other good advice!
