Australorp & Silver Laced Polish... hens or roos?

[KealakekuaChick]

Three 5 week old chicks that I am curious about. The Australorp is very docile and I am thinking it is a pullet. The Silver Laced Polish ("SLP #1") is extremely feisty and carries his tail like that constantly. He has a larger top notch than the other Polish and many more/larger tail feathers. Thinking he is a roo, but unsure of the other Polish. Leaning towards hen for SLP #2. Any ideas?

Your australorp looks like a pullet, and with that Mohawk, I'd say your polish is a male

I have a white egg laying Australorp, silver laced polish and want to breed them like this!! IMAGINE THE EGGS.
