It looks like s/he's some sort of cuckoo color, but I don't recognise the breed. My best guess would be hatchery-quality male sexlink, but that's only a guess and a highly unsubstantiated one.
Wait and see, maybe?
The silkies look like pullets, thus far, but this is the breed where breeders stand around the cages at shows and have guessing games, so, you know...
The fourth set of pictures (white) is a cockerel. No idea what breed.
#5 (white, normal feathers) looks like a girl so far, whatever she is...
