The implications of being "born in a manger"

A very interesting video, expressing some thoughts that are not commonly heard.  Not discussed by this narrator is the possibility that the manger was also filled with water and used for the birthing itself, rather than just as a crib.

After viewing it, I began to wonder if there was any connection between "manger" and "mangy."

"Manger" is from ME/MF mangier from L mandiucare = "to chew, eat" (as explained in the video), while "mangy" is the adjectival form of "mange" (skin disease) from MF manjewe = "itch."

However manjewe is derived from mangier; I can't imagine how that happened - perhaps through alternate definitions of the words.
