This makes the most sense from the data we have. The only thing I’d say is it seems strange for all the parents to be atypical genotypes. Where are the different bloodlines from?Yes, those numbers are definitely big enough to tell something. That's close to a 50/50 split of two colors, plus one other.
If these are all coming from White Cochins, one possible genetic explanation:
--one parent is pure for recessive white, the other is split for Dominant White and not-Dominant White. Most likely the hens are recessive white and the rooster is the one split for Dominant White, but it could be the other way.
That makes 50% of chicks be white, the other 50% show color: a split of 8 white/10 colored is almost perfect for that ratio.
--the rooster and most hens are genetically splash (but that is hidden by the fact that they are white.)
That makes all their "colored" chicks be splash, while the ones with Dominant White just look white.
--one hen is genetically blue
With a splash rooster, she will produce 50% blue chicks and 50% splash chicks, with half of each color actually looking white (because of the Dominant White). Depending on how many of the chicks come from her, that could account for there being only one visibly blue chick so far.
Note, there are plenty of other possibilities. A larger sample set will help decide which ones are actually more likely.
