The dropping is a little watery, nothing to be worried about by itself, as she's probably feeling a little bit stressed out.
The fact that she's able to pass the dropping means she isn't egg bound, but it also doesn't mean she can't become eggbound.
It's hard to tell from the photos if she's about to lay. Is she spending more time in her nestbox? Is her abdomen bulging? With my GCC, it becomes apparent that she's going to lay about 2 days before she actually lays.
If she does become egg bound, it can quickly become life threatening. But it's a tough call as to when to see the vet as it's also best to avoid stress and keep her in a familiar place if possible.
