My BCM from zgoatlady and my BCM from Cowgirlgrace both lay eggs that dark. They fade a bit later in the summer, but they are coming out dark again.Make sure you see egg pics before you buy birds. Not all Marans lay eggs that dark (those are extremely dark, and will be hard to come by, definitely won't find that dark of an egg from a hatchery bird) and all olive eggers lay different colored eggs. Egg color in neither the Marans or the OE can be guaranteed unless they are already laying.![]()
