Sexing 3 Month Old Buff Orpingtons

[Mrs. K]

I have had a lot of BO birds. At week 15, anything with a small pale comb is going to be female, pretty confidently. BO's tend to be slow to mature, so anything with a bright red comb, and wattles I would be confident are male. Check their legs too. Bigger thicker legs often indicate males.

Orps are pretty easy to sex. Just look at your group and see how some of them have MUCH bigger and redder combs and wattles than others. Those are your boys.
