I agree.The reds look like sex links not hatchery stock Rhode Island Reds. Same quality layer, just saying it's not RIR.
The other is likely hatchery Barred Plymouth Rock. From the photo it looks as though the legs are white, but I assume that's the photo. If in reality there is no yellow on legs at all and are white then it's a Cuckoo Marans. When she starts laying they would be dark brown eggs but I believe it's Rock.
