What breed are these?? And gender guesses?

[WPchickens]

In the first photo (shows all 6 chicks), I think I see 4 Delawares, and I'm not sure about the other 2. Austra White sounds like a good guess.


Delawares also have white barring across the black parts, while Columbian Wyandottes do not.

OP's chickens have single combs, and the Columbian pattern WITH white barring, so they look like Delawares to me.

The older they get the more like Delawares they look so thank you for helping confirm
