This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 麏 is uncertain. It visually combines 鹿 (deer) with 君, but the original semantic and phonetic roles are unclear.
The deer enclosure 鹿 surrounds 君, but without a clear meaning, picture a deer-like creature whose name is lost to time.
For キン, imagine a king deer (君 means ruler) inside the enclosure: king -> キン, and the deer is the king of the forest.
