Brian, there are several kinds of grizzle, but they are dominants and all work the same way. In such a mating you described, (grizzle x non grizzle) you can expect to produce 50 percent of each. Now you might get six grizzles in the first three rounds, then two non grizzles in the next. If you stopped there, you would have 75 percent grizzles as opposed to non. But the law of averages is based over a period of time. If you were to breed that pair and produce 25-50 offspring, chances are it would be right on 50/50.
If you use a bird that is homozygous grizzle, then yes, all of it's offspring will be grizzle.
If you mate two het grizzles together, 25 percent will be homozygous, 50 percent will be het (regular grizzle, one dose) and 25 percent will be non grizzles. Yes you can raise a non grizzle from two grizzles, but it won't be many.
Brian (the other one...lol)
