I am thinking 2 girls and 1 boy. I think the one on the right side of the picture with the longer feathers is a girl, the one in the middle is a boy and I "think" the one on the left side is a girl. I can't see her feathers as well as the one on the right.
Thank you Steffpeck. Funny I was thinking the one of the right was the boy since it was bigger and had thicker legs and the only one developing a comb yet. Here are a couple more photos.
