the newly hatched bird was a tired little fellow, and the first thing he did was to take a nap. he was cold, too, although the weather was fine and sunshiny. his down was all wet from the moisture inside the egg, and you can imagine how he felt, after growing for so long inside a warm, snug shell, to suddenly be without it and know that he could never again have it around him. even if it had been whole once more, he could not have been packed into it, for he had been stretching and growing every minute since he left it. it is for this reason that the barn-yard people have a wise saying: "a hatched chicken never returns to his shell."
