GCC's are the best
I got Chico first from a pet store about 12 months ago. Poor thing had psittacosis so he had to go to the vet to have one injection a week for 6 or 8 weeks to get better.
About 6 months after I got him he was very unhappy with me working all the time and my vet was looking to re-home her GCC because she didn't have enough time to spend with him so I took Greenie home as a buddy for Chico.
Greenie is now about 3 and Chico is about 1.
They got off to a rocky start (mostly due to my inexperience with introducing new birds) but now they're best friends and live in the same cage.
Greenie thinks he's a sun conure because he was homed next to a breeding pair for those 2 and a half years so he can get quite loud when he gets upset.
They are the cheekiest pair of birds, constantly stealing each others food just to throw it on the ground so th other bird can't eat it, always bathing in their drinking water, sometimes Chico will even hold down Greenie's claw when Greenie is trying to walk somewhere.
Wow, it almost sounds like they don't like each other but I can assure you they do love each other

They are the funniest pets I've ever owned!
