I have a clipped cockatiel. He's been clipped all his life. The breeders clipped him and I stuck with it for safety reasons. Now I've been considering whether to let him fly or not. The safety reasons really worry me but I want to know if he'll be happy. He's eighteen months now so his feet are really strong and he can run quite fast. He's developed excellent climbing skills too. But I wonder if he'd be happier as a flighted bird. Any suggestions?
