Keep a close eye on her. A lot of hens hunker down to the nest when their babies internally pip, and can't be pried off the nest with a shoe horn at that point. That she came off to eat with pipped eggs, may indicate that she will abandon them as they start to hatch. I had a hen who was a great setter, but she abandoned the eggs when they started hatching! Happy to sit on quiet eggs. Taking care of noisy, demanding chicks... not so much!!!
congrats on your new little featherballs
please post baby pics when you can get some good shots!
