Was this just a coincidence or is it genetics?

[Wee Timmy]

I recently got a frizzle Cochin rooster and I bred him to my smooth Cochin hen in the hopes to get more frizzles. I hatched 12 of their eggs and the chicks are now 2 weeks old, and they are ALL smooth feathered?? I understand the frizzle gene affects roughly 50% of the offspring when bred to a smooth so what happened? Is this just a big coincidence or is genetics at play?

you were just unlucky, when you hatch less than 20 chicks is luck of the draw, had you hatched 100 or more the outcome of the cross would have been closer to 50% - 50% it's called "Law of Large Numbers"

Guessing there's no way to be mistaken that he is frizzled.
Frizzle is pretty obvious.
Coincidence.
You're correct that his offspring has a 50/50 chance of being frizzled.
And it doesn't matter if you hatch 12 or 120 it can be close to 50/50 or highly uneven one way or the other.
That's just how it works when playing odds.
