After a period of not laying in late summer, one of our "Easter Egger" type Araucanas, Sonya, laid a few brown eggs instead of the regular turquoise greenish blue we're used to. It's never happened before, to our knowledge. I did read somewhere where it's the bile from their bile duct that adds to the green color (?)
She seems healthy, happy, energetic, and she's well fleshed and looks perfect. And I have no doubt it was little Sonya because she likes to get into our hay barn to lay and I opened the door for her when she was desperate to get inside one day. After about ten minutes, there it was, a brown egg. And a few more in the days that followed.
Anyone else ever have this experience? We've had Araucanas for years and never had one lay a brown egg.
