They are mixes. They don't match any breed standard. They might be easter eggers- often incorrectly called araucana or ameraucana.. these breeds have a standard with rules on what's accepted and neither of those do. Easter eggers is not a breed, basically a big giant group of freely bred birds for mixed color eggs, hence the term. Most EE have beard/muffs which makes many people think that's a required trait for an EE but again since they are not a breed, so really, anything goes. They may be something like EE bred with another breed, and they can lose the beards that way. The reason for EE is because your birds have pea combs and a huge majority of chickens with pea combs and non feathered legs are out of EE stock so that's basically a default guess.
Scarlet is definitely a boy- the color on the wing are the rooster feathers coming in. As he gets older, he's likely to get more of the same color on his neck and back.
Camilla is not showing obvious roo coloring but it kind of seems it is growing super shiny and pointy feathers on upper neck typical of roosters.. might want to wait a few weeks on Camilla to be sure.
