I begin with some seasonally appropriate science – the science of hatching chicks. What makes chicks peck on their shells and push their way into the world? A good question to ask in springtime, the season of baby birds, at Easter time, the season of baby chicks.
We might guess hunger inspires the chick to peck at its shell. There is some truth to that. By the time the chick hatches, it has exhausted its food supply inside the egg.
