Anyone know what breed chicks these are!?

New chicken owner here!
I was at my local TSC and ended up brining these babies home. They said 3 were Rhode Island Red and 3 were Tetra Brown. I'm not familiar with Tetra Browns so I tried looking online but they look more like Black Rock chicks and the RIR look like they should be darker and not the color I have.
Anyone know?

You have three red sex links (aka tetra browns) and three barred rocks.

I figured I didn't have Rhode Island's since they were so light. So they are Red sex links! Thank you for identifying them!
