I got this black coper maran supposedly a pullet couple weeks ago. I assume she is about 3 months old. She is aggressive towards my dozen other mixed assortment of pullets. This morning I found her jumping on my Americauna pullet and trying to pull hackle out. It seems like a rooster behavior. Can pullet also have this kind of behavior or I'm simplest duped gotten a cockerel? Thanks!
One more picture for clarity. She does seems to have thicker legs than others. I was told this is Bev's line Black Copper Maran. Pullet or cockerel?
That looks like a rooster and that sounds like rooster behaviour that you have described. Have you heard any crowing yet?
I'm pretty sure that is a rooster. I don't think pullets get the red in their shoulders/wings like that.
In my (limited) experience raising day old Blue and Black Copper Marans, it has always been pretty obvious by 3-4 weeks which were girls and boys, combs always larger and redder in the boys fairly early on--at that age I'd agree, you got duped, he's a he! (although it is not unusual for a hen to take over the dominant traits of a rooster if there isn't one there to begin with, including the jumping of the other girls, more as a dominance thing though, not a reproduction thing...but at such I young age as yours I'd definitely say it's true testosterone at work)
Pretty sure that is a male, females tend to not have near that much color either. Too bad, going to be a pretty boy though!
