Breed thoughts? Sold as ISA Brown & Rhode Island Red

[PookieC]

Hey chicken folks! I got 6 more lil chicks yesterday from the local feed store, seems the mad supply issues leveled off around here.
Anyway these were labeled as Rhode Island Red pullets (the lighter ones) and ISA brown pullets (the darker ones). I have minimal experience identifying birds, and have seen a variety of photos and info online regarding those breeds that makes me curious if these birds are in fact what I think! Doesn’t matter to me other than I love good information
So, do you think my breeds are accurate?

You got 3 ISA browns and 3... probably easter eggers or some other bym

I agree, the Rhode Island reds look right, but the others are definitely something else. It’s early yet to be able to tell exactly what they are, as a lot of breeds have that chipmunk look as chicks.

They do look very chipmunk
thank you both for responding!
