雏 means 'young / newly hatched.' The character is built from 刍 + 隹 (short-tailed bird) - 'the short-tailed bird that has just been fed.' 雏 also gives 雏形 (rudimentary form / prototype) and 雏菊 (daisy).
usage
Sometimes used metaphorically for a young, inexperienced person. The phrase 离巢的雏鸟 ('a fledgling that has left the nest') is a stock image for someone newly independent.
