So I understand that wing sexing and visual sexing can only be done with cross breeds. Is there any way to sex day old Easter Eggers, Australorps, or Cuckoo Marans? Are there any photos online to show vent sexing or what male and female vents are supposed to look like? I have seen the videos on sexing on YouTube, but nothing that really teaches you or shows you what to look for. I also understand that vent sexing is a skill that takes years and years to master, but I'd like to try it on my chicks when they hatch on the August 23. I have seen the post about Barred Rock sexing, and can try to use that on my Marans, but what about the other 2 breeds? I've also seen the post on Americana/Easter Egger feather pattern sexing of juvenille birds. I will probably use that as well.
