The blue egg color gene O (dominant, blue) and o (recessive, white) is autosomal, not sex-linked. Sometimes being homozygous (OO) produces a deeper shade of blue.
If your AB rooster is OO (2 copies of the dominant blue egg gene), you will get all blue egg layers if crossed with a white egg layer (oo). All will be heterozygous for blue eggs (Oo)
If he is Oo, the offspring will be split between blue (Oo) and white (oo) layers.
The only problem with using very light colored birds such as splashes, Cal Greys or Delawares in sex link crosses is that the new hatched chick colors are very similar, and males and females can be harder to tell apart. I had some gold-based autosexing Delaware crosses that all pretty much looked yellow at hatch.
