I haven’t noticed a correlation between bill color and sex with my Muscovy ducklings…the most reliable indicators are usually differences related to size (drakes are much larger) and sounds (drakes hiss and ducks “trill”), and I haven’t been able to sex by those at 2 weeks old. Would be an interesting hypothesis to test, though.
@brandy21410 , the duckling in question is the darker-colored one in the foreground, right? Maybe it’s the angle, but s/he looks a little larger than the others…is s/he? Also, are there any behavioral differences – more assertive/protective? They’re a very cute little group, BTW.
