The food and water an embryonic chick needs to de-
velop is present in the egg, whose yoke contains protein,
fat, vitamins and minerals. The gelatinous white serves to
store a constant supply of water. Besides this, the chick
needs to take in oxygen and expel carbon dioxide; they al-

so need a source of heat, calcium to develop its bones, and
a system to prevent bacterial infection and to protect
against physical trauma. The eggshell serves all these pur-
poses.
