Yep, poop training works!!

Clever birdies!!
I would leave them where they are and not change cages until she has completely lost interest in them ... but that's me.
A lot of people recommend moving them to a new area (cage in your case) because then they will feel unsettled and stop sitting on the eggs. Also, because of the change she won't be inclined to lay more (Unsettled).
Maybe get some more ideas, and then make up your mind. Let me know what you decide!
PS - Gorgeous photos!! Your feathered family looks happy and healthy!!
