Hi! I'm trying to learn the "skill" vent sexing. But wow, it's tricky! The chick on the pics. is a 3-4 days old Chabo, and I think it's a boy? It has a very clear (not so clear on the photo ) small dark/shiny "button" (the area I circled) that I think applies to the descriptions I've looked at and read about. Have checked through some other chicks and some of them look nothing like this, they do not appear to have any "button" at all, are they hens? Then, it's a few that have a VERY small button (so small that it is impossible to photograph), hens? Here are the pics ... Do I even watch the right area of the cloaca?
