Big pet peeve of mine to answer people with the info there asking for.
everything else can come after.
Don't worry vent sexing can be really hard and not that reliable if you haven't had a whole lot of practice. and even then its hard to be accurate is what the pros have told me. just keep your fingers crossed.
Like Ki4got said even at 8-10 wks old it still can be tricky. best to wait for them to grow up to be certain. most people wait till there much older to attempt a guess. When people ask the male or female question and post pics everyone will look for male type feathers coming in and how big and red the combs are getting per the birds young age. at 4 to 6 weeks old is about the earliest you can see roos combs getting noticeably red and bigger than the pullets on the BLRW and that's pretty much all you can do on sexing baby BLRW.
