I completely understand that poultry genetics is a throw of the dice.....no matter what, you'll sometimes hatch out the odd white from black parents, the odd partridge from splash & blue parents......you take these risks and I understand and accept that.
What I DON'T accept, and never will, are the breeders who intentionally defraud buyers. I won't mention their names here, I'm not the only one who has been duped by them, and there would be no good accomplished by that. I'm a strong believer in karma, so I just let it go....
Now, with the lavenders...even when you breed known Lav to known Lav you still will get an occasional "mutt", and I accept that too. If the egg buyer is not willing to understand that risk, and accept it, they shouldn't buy the eggs.
Just my .02
