BCM ended up with Cuckoo?

[Daniellefox05]

Two pet question!
1- I was told this chick was Black copper marans. But someone said it’s a Cuckoo. Here is a picture of mama and dad! Is that possible?

2 I have a chick that is a suspected Roo and he’s MEAN to my others. We just got two more chicks today (adding to the 5 others already in the brooder) and he is like charging after them when they come to eat by him, and walk around. What can I do? Do I need to get rid of him? I am not opposed to a rooster but I will not keep a mean one.
He’s 3 weeks!

That rooster and those hens wouldn't produce a cuckoo.
Do you have a pic of the chick?

Sorry the chick is the same one pictured below that’s being mean! Haha

I wouldn't believe that chick came from adults pictured.
To come from those one of them would have to have a barring gene and it is clear none do.
