Its day 16 and I woke up with a little chick peeping and hopping around. Another couple eggs had cracks and were jiggling. Chick 2 and 3 hatched a few hours later, even though a different one had zipped all the way around before they had done much. He finally broke the top off partially but he's exhausted and just sitting in his egg, not unfurled his head yet or anything, but at least I know he is breathing.
