Of course the raptors that hatched in Jurassic Park didn’t survive!
There were maybe ten of them, and they didn’t have parents. They ran off into the woods, and the woods are full of snakes, rats, possibly monkeys, probably birds of prey, and Compsognathuses that snuck over from Sorna and started breeding.
Even if a few of them managed to survive to adulthood, they had Dilophosaurs and a Tyrannosaurus to compete with (also Herrerasaurs, but they might have all been killed before the raptors would need to worry about them, unless they all ran into the Herrera paddock).
Yes, they’re a new apex species with no natural predators in the modern world, but it was still a brood of ten baby birds hatching and living on their own, without training or adaptation. Life found a way, but theirs were not the only lives.
