Hmm... It is standing really tall, but I am not seeing many physically characteristics yet.Between 4 and v5 weeks. I got it as female. But I've had other female bramhas before and they never stood tall or strutted like this one does.
I have a buff orpington that I was nervous about at 5 weeks too, but at 10 weeks she is not showing any cockerel traits, hopefully yours is the same way.
