Wood duck male or female?

[shegetsaround]

My neighbor found a hatching egg after the mother and other ducklings had left the nesting box. When will he be able to tell if it's male or female?

In about a month or 2

Is it a wild duck egg? If so, it's not legal to have the duckling.
Unless he knows how to vent sex and can do it safely, you won't know for quite a while.
With mine I can tell around 2 months.
