Sex and breed, (joyful maybe)

The first two photos are of a CLB from the white spot on his head do I presume he's a boy, in the second photo you can just about see the beginnings of a crest/comb too.

Photos 3 and 4 are what should be a red black araucana, but doesn't look like the baby chick photos i have googled, what do you think??  (I think I remember joyful having a liking for araucanas)

Many thanks in advance

Three and four have the chipmunk markings of breeds like Welsummer, Wyandottes. 

I have only hatched black, white and lavender araucanas although once did have a black/red cockerel. I wouldn't have thought a black/red chick would have those head marks so would be more inclined to say the chicks were an aruacana hybrid.
