I have 6 Mandarin ducklings. As usual I am heavy with males. Do you think I can determine at 9 weeks old that the ducklings with red bills are males? Some are really red and some look like they could be more pinkish/brownish/blackish. I'd like to be sure that the babies with red bills are in fact males and won't eventually turn brown. It seems to me that the brown bills may turn red but do the red bills turn brown?
