                      In general, both sexes incubate the eggs and feed the young. 
                      Most penguin chicks are covered with a sooty-gray down at 
                      hatching, although some have a pattern of soft grays and 
                      whites. Chicks of certain species remain confined to the 
                      burrow or nest through the entire nesting period, during 
                      which they are fed by their parents.  |
