Olive egger- supposed to be pullet- but is she?

[Earthwise]

Bought her as a pullet olive egger from a local hatchery. I know next to nothing about sexing chicks. The lady wasn’t sure what the parentage was who was there that day. She just knew their friends sold them olive egger chicks to sell at their hatchery. (My daughter actually picked her up that day since I couldn’t go so not sure of the details)
I’ve been looking online though and saw something about a white spot on the head of some breeds means it’s a male. Is this common across many breeds? Would a white spot on her head mean she’s actually a he? We can’t have roosters in our city so Viola would have to get a new home She has had this white spot since we got her and she is about 3 weeks old or so.

So far she looks like a pullet. Three weeks is a bit early to be confident though. Post updated pics in about 3 weeks and we should have a better idea.

Did Viola turn out to be a hen or roo?
