What makes it pink?

Salmon Faverolle eggs are described as “pink”. What makes them pink? One of our pink eggs had some straw stuck to the shell, and when I picked away the stalks, there was brown underneath. Which indicates that the pink color comes from a white layer that overlays the brown.

The inside of these eggs shells are white. The brown color is deposited in the oviduct near the end of the egg’s journey. So it looks like in Faverolles, the bloom (which is a protective coating deposited before the egg is laid) is more opaque, thus looks white, than other brown eggs. As an interesting aside, blue eggs are the result of a pigment spread throughout the shell, so the inside of a blue egg shell is blue. A green egg has the blue pigment over laid with a brown coating. Ah the interesting egg!
