10 week old, hen or roo? And breed question.

[Joeyjjj]

We bought these two as day old baby chicks two months ago. We were told the black one is black sexlink and grey one is production blue.

The black one seems aggressive these days and I've learnt that black sexlink hens should be solid black, so is it a rooster of other breed?

The grey one, production blue, which is not a very common breed. Does it look like a rooster to you?

First one is a Black Sexlink cockerel. I'm not familiar with "Production Blues" so I couldn't say for sure if that's the breed, but looks to be a pullet.

I agree, the first one is a black sex link cockerel. And I don't know anything about the breed of the second one, but I do think it's a very pretty pullet
