They are 6 weeks old, barnyard mix. First one has strange comb and I have no idea how to determine the gender of that one. Second one has largest comb out of these three, but I have a cockerel with a way larger comb, so still clinging to a (false)hope it's a pullet. Third one I could bet my money on it's a girl. It's my first year having chickens so I would really appreciate the insights of seasoned chicken keepers.
