I got the eggs from a family that keep french black copper marans, or so they said. Got 2 more in the bator waiting to hatch so will wait and see what colour they turn out to be. Oh and the eggs i got were very dark brown!!
Will take a pic and post in a few minutes.
I hatched some Black Copper Marans eggs and ended up with a chick like yours. It is now looking very much like a Blue Marans and absolutely beautiful. The lady I received the eggs from raises both Black Copper and Blue so I figure I got a little surprise present
