Do CCL's blue eggs get a paler shade of blue the longer they lay?
Do you mean in each egg cycle? Or the older the chicken? I've found that my girls follow a cycle with the first eggs being the darkest, and if they have brown pigment...the greenest. They get bluer and bluer as the cycle progresses and then lighter at the end. Then it starts all over again. My oldest girls are close to two year olds so I don't know what happens when the hens are "old"
