I bought a pair of Black Copper Marans and when I did she gave me some eggs to hatch. Three were BCM and the others were Blue Copper Marans I think. They hatched as three dark gray and two light gray. The pictures are of some of them after hatching and today. Are both shades of gray Blue Copper Maran? Two of the 3 black ones have weird wings. All have feathered out nicely except these two. What is the deal? The pictures aren't in the best order, sorry.
