Can anyone out here tell me how to tell if my birds have bonded? Spanky will be 2 in March and Darla just turned 2 in August. They spend all their "out of cage" time near each other, within 2 feet anyway. They will sit on the same perch together without a fight, the odd time they will lunge beaks at each other, but no serious fighting. I've been playing with the idea of taking one side off each cage, and putting them together, but I'm not sure if they are ready for that? They don't preen each other, at least not yet.
Anyone with experience please reply.
