The one with the brown stripe down the head is probably a Partridge Cochin, it looks just like that in day-old babies when thay arrived in the standard-sized Patridge Cochins I got this past June.
The solid light-colored bird is gonna probably be... white-ish , although I cannot tell what breed it will turn out to be since afterall, most chicks can tend to start out looking white-ish just like it.
Either Way ~ Best Of Luck To Ya!!
The chick with the v stripe down the head can't be a Cochin because there are no feathered legs. The chick could be a Pheonix, Welsummer, Dorking, there are many chicks that look the same as the striped one so it's hard to tell until they are a few months older.
