Hello BYCers! I have two Barred Rock chicks that I think are approx. 3-3 1/2 weeks old (feed store- not that specific with age). I have read in other posts that Barred Rocks are easier to sex early than a lot of other breeds, so I was wondering if anyone wants to take a guess at mine? The first two pics are of one, the last two pics are of the other. Thanks!
