Am I correct in fussing the breed

Hey I have 7 just over 2 weeks old. So their going through their ugly phase lol. But any pros out there that can distinguish the different breeds that can help .


Ok so the first I am sort of thinking wellie or barred rock. She had the markings similar markings of a wellie.



This one I am completely baffled on, when she was a day old she was brown with a yellow around the face.



And the last I am thinking RIR or sexlink as they had the two yellow/ brown strips down the back
