Both look like Easter Eggers to me. The mostly red bird looks like a cockerel, and the other is a female. I'd also guess that these are under five months old.
Pictures from the side would help - at first blush my guess is EEs - cockerel (red) and pullet (dark bird) likely under 20 weeks.
Both are Easter Eggers. The one on the left is a rooster, and the other one is a pullet. I agree with Wyandottes7 and BantamLover55 that they are probably a little less than five months old.
