That is an old wives tale that dogs can have a double or a delayed insemination during a single cycle. Most pregnancies take place during 12-16 day of a bitches cycle when mated, and pregnancy can only happen once only one sperm cell can make it and all the other sperm cells die off.
The runts are from poor genetics and BYBs & PMs breeding there already smallest chis hoping to get even more runts. However, if a healthy line has been proven of small chis like 3-4 pounders which is what most show chis are then you can keep a good line going. I am not saying that even in a healthy line there won't be a couple of defects, because that happens in any breed of dog, it's just the way genetics work, eventually weak genes will show through a line in some generations.

BYB and PMs will let the male and female mate several times and the due date is from the first breeding that took. So if allowed to breed for 5-7 days a pup can be 5-7 days early and a runt. Since they are premature the skull is not full formed along with other things, lungs etc just like a premie human.

I told her, "Nope, she doesnt have one" as soon as I saw her feeling her head lol is there any rhyme or reason as to which pups have that soft spot? Or is it just random?

It is where the skull has not completly closed so only skin and membrane sheilds the brain. Your vet would know if your pup had one and should have warned you.
