I read somewhere that you can tell if a mucsovy is a boy or a girl by looking at the end of its beak. color=boy, no color=girl. is this true? if not, can you tell them apart? most of them are about 5 months old. was wondering because my cousin has a bunch of them and his daughter want's the brown one to be a girl, but I think it's a boy. post pic tomorrow if i see it. they're free range and like to spend the day across the road in an old softball field.
