Our roo is 5 months and doesn't seem to be aggressive, but he does seem to guard the girls. When we're around him, he'll look at us and maybe stand tall, but hasn't made any moves. He will run to me for food and seems pretty sociable, but a bit guarded. Could he turn aggressive as he gets older or should his temperament be pretty set by now? I have small kids, so I'm really careful. If he's doing to suddenly get aggressive, it would be good to know in advance LOL. What is the point of crowing? Ours seems to crow randomly, but thankfully not all the time.
