Just had to post this. I've never had dark egg-layers before and was soooo surprised and amazed to find these in the coop over the past couple days! I think one or both are definitely the product of the pullet who is supposedly a BCM/RIR cross (but maybe pure BCM because of the darkness of those eggs?); I also have an Olive Egger who might have laid one - she has a pea/single comb so might not have the blue egg gene. One of the eggs is huge with black speckles; the other is darker, smaller, with a reddish hue to it.
