One of my husband's co-workers has recently hatched several clutches of Magpie ducklings, and he is giving them away. Great news for us! The ducklings are 2-3 weeks old, and none were vent sexed at an early age... So he has no idea which are male or female. I know there really will be no way to tell now until they start quacking (or not), but I also know there are some really experienced folks in this group. I figured it couldn't hurt to ask -- are there any kind of behavioral or physical traits I should look for that might make them more likely to be female? Any hints at this age, even though they wouldn't be 100% certain? I have one female Ancona and four males (all around 16 weeks), so I really do not want to end up with any more drakes. The more girls the better at this point. Fingers crossed... We're going over there sometime this weekend to bring our new babies home!
