I'll have to take some new pictures but I have 5 Blue Partridge babies in a grow out hutch right now and I think I have two definate girls because their crest are solid blue and they have not comb noticable. I also think I have two definate males as well because they have pronounced combs and little crest plus they are more red than the two I'm pretty sure are girls. I have one though I'm unsure of. Her/His crest is inbetween and just blends in with the rest of her/his body. He/She has no noticable comb though so I'm not sure. I'll post pics after bit to show.
