What is the meaning of fulfledge?

The term "fulfledge" is not commonly used in standard English; however, it appears to be a variation of "fledge," which refers to the process of a young bird developing the feathers necessary for flight. In a broader sense, "fulfledge" could imply the completion or full development of a process or skill. It's often used metaphorically to describe someone or something reaching maturity or readiness.
