Help with identifying breeds?

[feathryfrnds]

Still fairly new to chickens. Grabbed some rainbow layers hoping some of y'all might help me figure out what breeds these are. There are four total. Thinking the 1st might be a buff orphington? Thanks in advance!

If the wing feathers come in buff on the first one, then it probably is a buff Orpington.

I think the other two are Easter eggers.

1 is orangish and a lot "fatter" than the other chicks which made me assume buff orphington. Not sure what it could be otherwise. More pictures now that they're under a brighter light.
