Definitely not the case. Chances of getting white chicks when a parent is not white are at best 50/50. And that is only if the non-white is split (has one copy) for white.If not split, then none of the chicks will be white. It is pretty universally agreed that if you want to breed to the standard, you do not mix whites and non-whites unless you have some pretty good knowledge of the genes carried by an individual white.
For instance, if you breed a two correctly coloured birds of the same variety together and get a white chick, you learn that each of the parents is split to white, and you knwo from the parents what pattern and colour genes that specific white carries. You can reliably breed it to that variety, knowing that the offpsring will be split to white, but will also inherit the colour and pattern genes of the variety. A different white bird will not have this specific set of genes.
