I wanted to start an emu sexing experiment. If everyone who hatches out their emu chicks or gets a young chick, take good pictures of the tops of their head... the patterns, and check in now and then with new pics as they develop and see who ends up being boys or girls, especially if you have them DNA sexed ( speed the process along) LOL. Note anything different about the boys or girls as they develop... like theblue skin color goes down 3/4 of their neck in one vs 1/2 on another... etc. etc..
