Sexing bantam cochins

[Thopkin2]

These ones were born May 20, and they're a new breed for us. I understand they take forever to sex but is there any way to tell before they crow? They're all so friendly I'd hate for them to all be cockerels.

Also, any ideas on colours? Will my speckled yellow/black baby be mottled? She has white coming in amongst the black. And finally, is the lighter one blue or also a black like the third?

I think the first one is a ceckerel. He looks blue to me. The black one looks like a pullet. I'm not sure about the last one.

First two look male, second seems to be female for now

They'll be 8 weeks on Monday so here's an update. #1 blue, #2 black, #3 maybe blue as well.
