Yes, they're all flighted, although Ziggy, my Ekki came to me clipped at the age of 10, and had never learned how to fly. However, with that being said, he's a master at hopping off his cage, strutting over to a nearby cage and harassing the heck out of that bird. He's not a fan of his birdie neighbors.
I take my birds out in groups. The smallest: 2 duskies, and pineapple GCC come out together. My CAG, Pan Am and Ekki also come out together. My Jardine's comes out separately, simply because he's a baby and I'm not quite certain yet how he'd fare mingling with the others. My caique also comes out separately due to his unpredictability.
