Pullet or Cockerel?

[Sneaky Chicken]

I am hoping for some input on my GLW chick, Ginger, who is about 5ish weeks old. We started seeing tiny waddles grow in the past couple of days and are wondering if she might be a roo. Of the three of our newest babies, she is the most skittish. Can anyone help?

At this point, it appears she's a she.
