Black Australorp roo?

[Fallen Leaf Farm]

So, I can spot the Buff Orpington roos at a week or two old. This 7 week old Australorp has me concerned...I can't have another roo! I have gotten "Pullets" from the feed store 3 times, and if this one is a roo, I have gotten a roo each time. They say it's a 10% chance of them being sexed wrong. I am running 3 out of 22, much worse odds.

The one in question is in the front of the picture:

I saw pullet...

my roo

my pullet, at about the same age.

I'm thinking roo.. The saddle and hackle feathers look rather pointy, and the wattles at least look too red for it to be a pullet at 7 weeks.

The baby looks rooish to me ...

It looks kinda like a pullet to me, but it might be too early to tell

Your odds are bad

Roo...is my vote.
