I am looking to purchase this breeding group, but want to make sure they are really French Black Copper Marans before I make a cash offer. I also have no idea how much to offer for them. This is the group according to the email: First pic is what the 3 hens look like, second is the rooster, and third pic is of the young, 3 roosters and a hen. These are French Black Copper Marans Thanks in advance for any help. I am new to Marans.
