“Within sight” was something of a misnomer. In fact, they were up on the cliff above the nest. Aket-ten and Re-eth-ke had come in first, realized immediately that the first of the eggs was hatching, and cut off Avatre, Kiron, and Nofret, waving them up to the cliff. Kiron was more than willing to follow her lead in this. He had never seen a dragon with hatching eggs before, and according to Ari, they got positively bloodthirsty until all the hatchlings were safely out and fed. He had said that they should all hatch nearly at once; dragons didn’t start incubation until all the eggs were laid, so that there wasn’t much more than a day or two between the oldest and the youngest.

One of the five eggs Coresan had laid was clearly infertile; she had pushed it off to one side, out of the nest. The others were moving, one violently. And it sounded like there was tapping coming from all of them.

Suddenly Coresan stopped prowling, and practically leaped on the egg that had been moving the most. Trapping it between her foreclaws, she tilted her head to the side, and—

Kiron watched avidly. He knew what must be coming. Dragon egg shells were thicker than the walls of water jars and a great deal less fragile; they had to be, to contain the developing dragon safely. But that meant they were hard. He, Ari, and every other human that had ever helped an egg to hatch had been forced to use hammers to help the baby inside crack the shell. But no one knew how dragons assisted their young. Not even Ari, who had studied dragons nesting in caves to keep the hatching young out of the rains, and had been unable as a consequence to get close enough to see the crucial moment.

He, Nofret, and Aket-ten would be the first humans to witness the event, and it would solve a great mystery, for dragon teeth were hardly formed in a way that would let them be used like hammers or chisels, and no one had ever seen a dragon pick up anything in its foreclaws to use like a tool.

Coresan tilted her head to the side, listening intently to the baby within. Then she bent to the egg, and licked a spot on the top. Then she waited a moment, and with the tips of her very front fangs, began scraping at the same spot. Then she stopped, licked, waited, and scraped again. After the third time, Kiron realized that the shell where she had licked was flaking away.

“Something in her saliva must be eating at the shell!” he exclaimed. “Or making it more brittle!”
