When I purchased my pullets in May, the local farmer/chicken raiser convinced me to buy some BCMs. I didn't give a flip what color of eggs I had, but I do love those chickens. My ideal flock is half Buff Orpingtons and half BCMs. (This is Pittsburgh Steelers country--everyone comments on the BLACK & GOLD!!) The BOs have been laying for almost a month; I finally got the first dark brown eggs! Yeah!
I recently attended the Bloomsburg Fair, the largest in Pennsylvania. There was a whole barn of chickens being shown. I was shocked that there was NOT ONE Marans of any sort. Why is this? I feel lucky that I listened to my farmer--I guess BCMs are not very common around here.
Anyway, our black-with-no-copper Marans has the most gorgeous iridescent feathers. Like the Rainbow Crow book. Our black-with-copper Marans is the least nice of our birds. I had some hens killed by a dog, had 2 out of 3 Marans killed and replaced them with one BCM, so the 'mean' hen was part of the flock addition--she doesn't seem to like not being at the top of the pecking order!!
BOs and BCMs are some sizable birds, lol.
