Same chicken laying white and brown eggs?

That's more what I'd expect from a brown egg layer.

If the are mixed breeds instead of just one could that cause the color of the egg to flex? I got them all from TSC.

Is this even possible?!?!

Very possible. Brown eggs are a brown coating on a white shell, sometimes the coating can miss a beat(spray booth glitch)....and the coating can naturally fade over the laying season, can be darkest at onset of lay after the molt/winter break then fade as the summer goes by.

So yes, the brown coating can vary....and the heat could have something to do with it.
Nothing to worry about.
