What gender? EE and CCL hens over blue australorp roo

[Oldpony]

Hello! I posted these a while ago but was told they were too young. I wrote a reply to that post but not sure it will show up so am posting here I hope that’s okay. I am wondering if anyone can tell me the sex of these chicks, they are six weeks old. Crème crested legbar and black easter egger hens with puffy cheeks over a pure blue australorp roo. I think two have crests but not sure? Any ideas are greatly appreciated I am so excited thank you.

None of them scream cockerel to me at least not yet.

The chicks coming from the CCL will have barred males with head spots as chicks and non-barred females with no head spots. Won't work for the chicks with the Easter egger as the mother, though, unless she has barring.

The blue and black with crests are pullets. As JedJackson said that pairing will produce sex-links and those appear to be solid. With the two Australorp/EE the black looks like a cockerel, the blue possibly a pullet but it's still a tad young to be sure

Another update! I am wondering if the first is a roo? He’s giving too energy but the others seem like pullets. Thank you for any thoughts!
