I adopted two GCC's (approx 2 years old?) less than a week ago. They enjoy getting out, landing on my shoulder or head, and then refusing to go back into the cage. And yes, they bite...I'll research that one later. They've been out for the last three days, I leave the cage door open so they can access food and water but sometimes, for their safety and my sanity....., they need to get back into their cage with the door shut! I'm new to birds, what's your advice??
