OK, here's my question. I have four Olive Eggers pullets that a breeder snuck in on me when I thought I was buying purebred Marans. They have just started laying, and today. I saw one of the Olive Eggers in the process of laying an egg. It is brown and approximately a 2.5 on my Marans egg color chart. Howe often does an Olive Eggers lay the somewhat darker brown eggs? I know she is an Olive Eggers by the presence of the muff and beard. I have yet to see even a slightly greenish egg. The Olive Eggers are part of What I believed to be a purebred Marans flock.
