I've got two roosters now, and one possible cockerel (EE) in the grow out pen. I've found (and this is
very generalized) that very friendly cockerels often turn out to be terrors as they get older. Those that respect your space tend to be better keepers. But one of my current roosters would attack my dust pan every time I cleaned the brooder, from a very young age (he was purchased and supposed to be a pullet.

) . He's 4 years old now, and a really, really good roo. Gives me space, has never attacked anyone, even my very young grand kids. Until they mature some, you sometimes don't know for sure. But I've had some very friendly, cuddly babies that were Satan reincarnate when they matured too. There is a reason that 'Lucifer' is a common rooster name.
