sounds like I need to get in contact with Mr Jerry.
eta: dangit slow me. so, the double blue, would mean the shell is blue, AND the cover is blue?
The Am hen I hatched from his eggs is double blue, but I can't speak for all his Am's or his Legbars being that way... just make sure you ask him if any of his are single blues... if there's any possibility of single blue egg carries, you wouldn't want to use the roo since there is no way to tell if he carries single or double until you test mate him and his pullet offspring mature and start laying... make sense?
And no, there is no 'cover' in the blue eggs... blue eggs are caused by a single gene (technically it started as a side effect of a retrovirus) and a bird can have 1 or 2 copies... brown eggs are caused by a coating similar to the bloom or a paint, if you will... that is controlled by at least 15 genes, I think? Thus the many varied shades of brown eggs...
Blue color actually saturates the entire shell itself... most of the brown can be scrubbed off, blue cannot... or crack open the shells and if you peel off the inner membrane the inside of a brown egg shell will be white, the inside of a blue egg shell will be blue...
Think of the blue this way... cup of water, put a single drop of blue food dye in it and stir, single blue egg gene... add a second drop and stir, double blue egg gene... the water simulates the whole shell, not just the outside... make sense?
