Too early to know the sex?

[Twhi7]

My coturnix quail are 2 weeks old exactly - is it too early to know if they’re male/female? I attached a picture of 3 of them. They look like females because of the speckles on their chest, but I’m assuming their feathers can still change. What do you think?

Thanks in advance!

Those look rosetta to me - not feather sexable.
