Yes, they can be big pets. Mine still follow us around and peck our shoes from time to time. lol
I'm really hoping I have a roo. I also have some 3-4 week old chicks we have not quite figured out what they are yet. But I really want a roo. Might have get one from my dad. He has 2 roo's right now.
I just got mine back in April. So I really don't know much about them, mine are not loud at all. As for their temperment they are pretty friendly. They don't like for us pick them up to much anymore.
I don't have a roo though. I don't know how to keep them quiet.
