Does anyone have some good pictures of vent sexing young birds? I've read articles that say to look for a "bump", but they don't say where the bump is. Is it the part that you press on a fully adult male to get foam, or is it something in the cloaca? I want to get better at vent sexing birds at 4-5 weeks. I get so many requests for young hens and I don't want to tell someone "I think this is a hen, but I could be wrong since it's young," and have them get upset when it turns into a roo.
