Is it possible this splash roo with red bleed [his close cropped wings removed a lot of red feathering] could have produced white with red chicks from Speckled Sussex or Black Laced Red Wyandottes?

Here's the story:

I sold my neighbor several dozen hatching eggs from the breeding pen with the above roo and SS and BLRW hens, plus some blue and green eggs from another pen containing one blue Ameraucana, one black Ameraucana, and three "wild partridge type" EE hens; under two Dark Cornish cockerals and a huge Cornish Rock meaty. I was having expected fertility problems in the second pen, but was still a little surprized when he said none of the blue and green eggs hatched. I was very surprized, however, when he said he hatched a white chick with green legs from a tan egg in the first group. I figured the big CX had finally managed to get an EE fertile; and that the third party doing the hatching had missed seeing the hatched green egg.

The second hatch is done now, and there are 4 or 5 more whites in it, and again he says the hatcher reported no blue or green eggs hatched.

The first chick is well feathered now; its a white pullet with red head, green shanks, pea comb, and scant muffs. The younger ones are beginning to feather. the down is pure yellow on one, yellow with orange stripes and head patterning on another. Their first feathers are white with some looking like young white laced reds or jubilees. One either has a very poor pea comb or a single, the rest have pea combs. Shank color runs from bright yellow to green. [The splash roo has dark slate shanks, was purchased from a breeder as a pure Ameraucana as a chick; I consider him an EE due to poor type and heavy red bleed.] The rest of the chicks from the two hatches are either solid blue or blue with some gold or red showing, to red with blue patterning; that was what I expected them to look like. What's up with the white chicks?
 
If you are getting adult white birds, then one of the parents is dominant white. I believe the splash roo is heterozygous ( split) dominant white and not splash. He only carries one dominant white gene.

Thank you Tim. He was supposed to be an Ameraucana, but I always considered, and used this guy as, an EE, but never thought he might carry dominate white [his base color was the grayish/off white of splash blue, but his type alone was all wrong for a pure Ameraucana]. I sold him last month as an EE to go over some barnyard mixes a guy has; he should get an interesting spread of colors.
