Help Sexing My First Quail

[fuzzyandchippy]

I am new at this and these are my first quail. Based on the pics does anyone have a theory on sex of each? They are four weeks old.
From what I have read, it sounds like the speckled are female and the plain brown chest is a boy?
Thanks so much

The one on the left is female, the one on the right is male.
Females have the spotted breasts, males have the red.

Yep, females are speckled and males are plain reddish-brown
