Need help with black copper maran!

[Rybakswife]

So I’ve posted before about my Black Copper Marans and was able to place all my cockerels to good homes but one of the Black Copper Marans that I have kept I can’t tell if it’s a he or she??? My black copper maran will be 7 weeks on Friday. Also since placing the other cockerels this maran has been aggressive he has bit my kids when they go in the brooder to pet the other chicks he is also attacking all the other chicks who are the same age which I had to remove him/her by themselves to a brooder all alone I have tried twice to put him or her in the other brooder with the other chicks and still immediately goes after everybody and bites them and they all cowered to one corner of the brooder and won’t move I need help on what to do and tell me if this is a he or she??

7 weeks? Yes, I'd say cockerel.

That seems mighty agressive for such a young age. Maybe? I only have a couple very sweet roosters...so my experience is lacking...but, I wonder if he'll become one of those mean roosters? Sounds like you won't wait to find out. He'll do better being in a flock 'under' a more domineering rooster (maybe?). Especially since this behavior started after removing the other cockerels.

Yes I thought 7 weeks was a little young to start agressive behavior this is my first set of chicks of my own I’ve been raised with chickens my whole life but have never had been around an agreesive rooster and if there was ever one they didn’t last long around the Farm, So I’m wondering if he will do better at a farm like you said with a more dominant rooster that can put him in his place.

7 weeks with a comb that big... there's no doubts.
