Zaros would not have known about the stone, but that does not mean that the stone could not have been what he sensed.
For one, the stone was fundamentally altered from its original state, easily dofferentiating it from Jas and any other eggs.
For two, there's nothing to indicate that any other eggs would have been laid whilst the elders were still on Freneskae. I personally find it more likely that they'd wait to lay their eggs on the perfect plane rather than all lay their eggs just after they hatch and then need to lug them around as they make each plane in a cycle.
