Help spot the Roo(s)?

[HogFoo]

Trying to figure out which of our 10 new chicks, if any, are roosters. They are ~19 weeks old and I know you're supposed to easily tell by now, but we're wondering/wanting to confirm about three of them shown below. Each has a slightly different story. Would appreciate any help you can offer. Thanks!

Buff Orpington
This one is the biggest question for us. We think he/she acts like a rooster (hates to be picked up and steers clear of us unlike everyone else, gives you the stink eye, is more aggressive than the other chickens, etc.), but isn't the body more like a pullet?

Australorp1
We think this one is a rooster by looking at it (tail feathers, etc.), but it sure acts like a hen. Not at all assertive among the other birds, a bit shy if approached, and will actually squat when I get over it to let me pick them up. Roo dominated by hens, roo lower in the pecking order, or are we just off here?

Australorp2
Finally, there's this one that we think is probably a hen, but has a more pronounced comb than the other Australorps we know are hens. Hen or roo?

They are all pullets, They should be crowing now if they were cockerels, and they would have most of their cockerel plumage.

Yeah, all pullets! Very pretty birds!

 

[Pullet Press]

x3, all pullets!

 

[LadiesAndJane]

I agree that they are all girls and the red combs means they will be laying soon!

 

[Chookwagn]

they look all very much like pullets to me

Thanks everyone. I confess, I’m kind of sad and relieved at the same time. We were hoping for one roo, but were also a bit nervous about it since we have young kids who love being with the chickens and didn’t want them getting hurt. Maybe down the road when they are a little older...
