At what age can we tell with BO's?

When can I start to try to figure out who's who?
This spring is our first straight run order.

Usually with all breeds I figure it out at 1-2 months old.

If I remember correctly, I was fairly sure who was the roo by about week 4. Maybe it was week 5? Dunno. It was pretty early in the game though. The rooster's comb just popped right up and then I could see red along his beak (future wattles).

I did have a BO hen that fooled me for a while. I thought she was a he until she laid an egg. She still has a comb that is twice as big as the other girl's.

I've learned a lot about chickens in the past two years, but the gender differentiation game has always baffled me. I may start adding pics in another week or or two. We're at three weeks now, and I have some big little birds with some big attitudes.
