Hi! My daughter received a pair of parakeets for her birthday, and I am confused about their sexes. The pet store said we had received a male and a female: the male being the one with blue coloring and the female with pinkish-purple coloring, but as they are aging, I'm not quite sure she was correct. Based on their leg tags, the yellow and blue parakeet is 4 months old, and the white and blue parakeet is 3 months old. Anyone want to guess their sex? Thanks for all the help!
