I hatched a mixed bunch of eggs and ended up with a bunch of Blueface, a wild colored, a golden pearl, a red breasted,and 5 silver. All but 1 of the Blueface were boys and have obvious rust colored vent feathers, so does the red breasted. None of the silvers have any pink feathers yet does that mean they are girls for sure or should I wait longer, they are about 3 wks old I think.
