pale blue I have noticed if the eggs get soiled at all they have a green cast where they are soiled also they can better make the blue shells dependant on what you feed them. I tested this out at one time ot makes a huge. Differance calendula pettles. I am in the process of moving and havent brought over herb yet so she hasnt had any for several months her eggs are more pale because of it.
Think I read somewhere in research about calendula. Also noticed my blue egg layer lays paler eggs as the season progresses. I don't post pics because my camera makes colors brighter than they are in reality so I don't trust posted pics of color - it all depends on the camera, lighting, website post, etc. Just like the pics of Marans or Wellie dark eggs I don't trust the depth of color on them either in pics. Thx 4 your input!
