I always hear that poor quality Marans lay the same color brown egg as Barred Rocks. Do people use that comparison because Cuckoos kind of look like Barred Rocks, or do most Barred Rocks lay a medium brown and not a light brown egg? I have heard that some RIRs lay a darker medium brown egg, but I always thought Rocks laid the lighter brown. I just ordered some White and Buff Rocks so I wonder what shade of brown their eggs will be...Thoughts??
