Marans egg color:

[dickseng]

We've been raising Marans for a couple years. This year I decided to sell some eggs to offset the feed costs and had a comment from a prospective hatching egg buyer that Marans eggs will lighten up considerably if they are given crushed oyster shell.
Anybody have any knowledge of this?

Thank you,
