I'm 99% sure the younger one is male, so he must be an early bloomer. I am attaching pictures which honestly aren't the best, I will see if I can get better ones. The first picture is the oldest in front, younger in the middle and mom last. No sign of brown feathers on the older one, but I've always felt she was a girl. I will wait to name this one till they are older in case it does turn out to be a boy. The second picture is of the younger one who I think is the male. If you look closely, there is a little brown under the wing. There is a lot more color that the picture doesn't show, the feathers almost look like pin feathers that are slowly being released. Parents haven't fed them in days, and babies are doing great eating on their own, although the younger one still asks often to be fed.
