your Lav's are pro covering blue... the white might be recessive white but dominant white should be visible in the parents...
So I am puzzled, but then again, I don't understand the genetic factor a whole lot either. Out of 7 OE chicks that are FBCM x Lav Am crosses I have ended up with 1 that looks like a FBCM, 1 solid black, 1 solid white with feathered legs and 4 blue chicks. All of them are pea combed. How did I get blue? Can the white chick mean that one of the Lav Am's carries a dominant white gene?
