Male or female immature wood duck?

[jlesz]

Hey everyone, I work at a wildlife rehab facility and we have been raising this wood duckling since she was just a little hatchling. Now that she is older, we can’t decide if he/she is a male or female. I’ve attached some pictures below. Thanks for your help!

In comparison, this is my female rescue wood duck at about 10 weeks.
