“The hatching of the eggs does not take place all at once; sometimes it is twenty-four hours before all the eggs are broken. A danger thus arises. Divided between her desire to continue setting and her wish to give her attention to the newly born, the mother may make some sudden movement and unintentionally trample on the tender creatures, or even leave the nest too soon, which would cause the loss of the backward eggs. What, then, is to be done? The first-born are taken as carefully as possible and placed in a basket stuffed with wool or cotton and put in a warm place near the fire. When the whole family is hatched it is restored to the mother.
