I just went out and collected eggs to find a really light pink one. I have 10 hens. All are brown egg layers with the exception of two that are EE (one lays Olive Eggs and the other more green/blue eggs) and another EE that layed about 3-4 (I believe they were her eggs and they were green/blue) eggs and then stopped. So my question would be, is this light pink egg from one of the brown egg layers or could my EE who stopped laying eggs that were green/blue, now be pink? Another question would be, what makes the pigment in the shell change color? Thanks for your help!
