That's the same situation with my Darwin. The woman who had her prior to me thought she was a male when she first got her, and by the time she had her DNA'd Darwin knew her name. She was 18 when she joined our flock so there was definitely no changing it then, it's one of the few things she says. I've always liked boy names for girls, anywayIt's ok! I originally thought she was a boy, but then discovered she was a girl, and why change her name? She knows that name and grew up with it!
