First one looks like a boy and the second one looks like a girl... As far as breed, the first one could be a bantam dark brahma roo... It's hard to tell with how young they are. Could be cochins. If they are bantams, there are only a few feathered leg possibilities and they definitely aren't silkies.
The D'Uccles are a porcelain and a blue both roos. The white is entirely the wrong shape for a Cochin. I think she's a poorly bearded D'Uccle. What kind of comb does the first roo have? If he has a pea comb, I would say he is either a dark or light Brahma (really messy color for either). If he has a single comb, I would say either a birchen or a silver laced Cochin (again, very messy color for either).
i cant tell on the d'uccles because of the lighting both are cockerels neither one is a blue as blues are 2 toned if anything its a lavender which is a solid even gray all over. they both sorta look like porcelains though, does the one of the left even have a beard? if not then thats a booted bantam instead of a d'uccle, which is what i suspect it is. if anything the white would be a booted bantam if not a cochin
The "blue" is a self blue which in some breeds is called lavender. I don't know of any hatcheries that sell Booted Bantams... Sure would love to find some though. I've had several D'Uccles that had little to no beard as chicks and would develop a bit of a beard when they were older. It's that whole "hatchery quality" thing that we battle with all the time.
