4-6 week olds. Gender and breed?

Update. Chick 6 is a cockerel and I'm still wondering if anyone else might have any guesses as to what my mystery girl is.
She's started laying light brown eggs. Perhaps her stance and proportions can give a clue as to what breeds she may have originated from?
My personal guess is that she has some brittish araucana in her. That would explain the crest and it would make sense for a colorful egg layer flock (which is what she came from) to have brittish araucana in there for those blue egg genes.
She's such a sweet girl and fits into my bantam flock just fine, despite her size.

She might have British Araucana genes, but since she has yellow skin and a single comb, she's unlikely to be the product of a direct cross with one. Pea combs and white skin, both traits of British Araucanas, are both dominant genetically.

I'm not familiar with breeds in Latvia, so she may be something local? There are tons of crested breeds in Europe. Swedish Flower Hens often have small crests like hers, as an example. If she was in the United States I'd say she's a mix of various breeds, with maybe Legbar somewhere in the ancestry.

It will probably remain a mystery, but since she came from an egg from a farmer she will probably be a good layer.
