Welcome to my pond - Swim, wade, or sit on the bank

Absolutely... one with single blue is easier to see into than one with double blue... blues are a harder one to see through, but the difference is like candling a regular brown egg layer egg, and a medium to dark Marans egg...

You can ask @WalnutHill if she remembers seeing a difference in some of my blue eggs for another opinion if you like...

Actually, I can get you comparison pics if you want... since I have that gorgeous candler K made...

gal, that would be awesome!!!

so long as I can make sure that both parents have the double blue, that would be awesome.....

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?

Hon, I think you'd have to borrow the proper equipment for that statement to apply... now Lamey on the other hand.......

Oh, I didn't know there was someone in particular being referred to..

(because I can certainly think of plenty on the other side that it could apply to!)

I'm not sure their vision is even that good. And though in nature, a lack of vision is often made up for by superlative hearing, even echolocation requires that the user has to shut up sometimes and just listen.

(I saw a few posts by the party in question. I was thinking that I would like to be able to send a virus to their computer that would surgically remove the exclamation point from their keyboard - I suspect they'd be too tongue-tied to post.)

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?

yes ma'm it does make sense........same gene, just two of them.

thank you very much, and look forward to seeing your pics.
