So I got a shipment of assorted brown layers 3 weeks ago, some looked like this:



I was told they were RIR. They now look like this (in background):




Newest baby came in, is either my "meal maker" chick or my rare breed assorted chick. Was told also RIR, but she is much darker with a darker stripe down the back:



Are they all RIR? Do I have something else?

the photo above looks like a welsummer or barnevelder and the photo above that there is three rhode island reds (the three brown ones) and is the black one mabey a marans?

Black ones are barred rocks...white ones I wasn't sure on either. So the top photos are indeed RIR?
