I am trying to compare vent sexing ducks and emu chicks. I have 2 emu chicks that are suppose to be females, but I'm pretty sure when i tried to vent sex the one I thought was my best chance of a girl, it has a long little white phallus... I believe. So what am I looking for in the female? The other one has a white pimple like spot in the same place, just not as big, but is the older of the two.
