The size difference doesn’t look nearly as bad in photos. Im probably just nitpicking.
They are HENS! Congratulations the others will catch up to the other one. My Aures have HUGE Combs that lay over to the side. I believe yours will too. The first bird to lay will be the one with the largest comb. I believe the combs and wattles will even get bigger yet. I;m not a fan of the big comb and wattles but the eggs are lovely.
