My roo has recently developed a penchant for aggression. He doesn't actually do any violence, he just threatens. The last couple of times I've picked him up and carried him for a couple of minutes. I guess I should do it for longer, but that's not my question. He's really quick and hard to catch. I've had to grab him by his tailfeathers to stop him. Is that a really bad idea? I don't want to make him mean, or bald-butted.
