Yes dimples are actually a good sign that they are close to hatching. They would have absorbed most of the fluids inside the egg hence why it sucks in. Ball babies are surprising resilient to our mistakes. Tho you still want to avoid mistakes if possible. I've seen eggs where the breeder mistook for a different clutch and cut extremely early and the babies were all fine. Like I said just let them do their thing abd they should do fine
