What breed are these chicks?

Here are a couple more photos showing a clearer view of the comb and coloring of the chicks. 3 have dark/yellowish legs and one is a lighter color and has pink legs.

I agree with the olive egger. I got a chick out of a clutch I just hatched that looked just like these chicks that came from a flock with a golden comet hen and olive egger or Araucana roo came out looking like these. I was told they’d be considered F1 Olive Eggers.

They have really grown the last few weeks. Three are nearly identical and are still looking like olive eggers to me. The one in the front is definitely different than the others. Maybe a Rhode Island Red or some kind of red sex link? All are healthy and seem to be thriving.
