In my mixed flock I suddenly found purple eggs. This is an established pen...no one has been added in over a year. I have 1 ee that lays a blueish egg shown. Here is the first picture...
I have black copper marans in the pen. A friend said that she found a purpleish egg in her bcm pen today. This got me thinking. What if there is something on my egg? So I wet the egg and it turned chocolaty brown. THEN, as it dried it turned purple again. Is there something missing from her diet to cause this? I wet a patch on the egg for you to see.
