WHmarans,I was very confused by that because I did not see the male down color call for a head spot in the sop i could find but the head spot seems like a strong male marking.
Since both the male and female CCLS chicks can have a dot on the head, you have to look for the chipmunk stripe (I look for it to be a triangle on the female). Then I look at whether or not the spot is big and spotty or faint. Faint plus the triangle means female in CCL. Big and spotty means male. And if it really confusing as to the sex, the chick should be marked and not used for breeding.
Another method is to look at the eye-liner. On a male, the white or silver patch can intrude into the black eye-liner. This is similar to how Welsummers can be sexed as chicks. The male Welsummers will have messy a messy eye-liner while the females will be dark and well-defined.
But as I said, if you cannot tell right away, you should tag the chick and think twice about using any chick with confusing autosexing markers in a breeding program.
Below is an example of a female CCL that had a headspot. In this case, the triangle is clearly defined, as well as the eye-liner. I need to take an updated picture of her at 8 weeks but so far she has turned into very beautiful girl with silver, cream, and absolutely no gold.
