Deflowered Hen or Violated Roo? (PIC)

[bluey]

Do to my inability to sex a chicken, even at 18 weeks, I have the following question. We have 2 Buff Orps that I cannot seem to sex. They are 18 weeks old and have never crowed but have had Roo-ish features from a young age.

Today my EE rooster mated one of the Orps. This one specifically:

Now, I don't know whether I should be pleasantly surprised to have a Orp hen or troubled that my Roo doesn't know the difference either.

Any help would be appreciated. Thanks!

It's a rooster and your EE was just telling this guy who the boss is around the barnyard. Dominance displays are what you're seeing.
