RE: ETA: Regarding the term "hatching eggs" I think my mail carrier misinterprets that phrase as well when she brings me "live hatching eggs". She thinks they are breaking through the shell at that very moment. ~~
Totally understandable, as the word "hatching" is a verb, as in, "The eggs are hatching." The term "hatching eggs" is a euphemism used by chicken people to mean "fertilized eggs that are capable of producing a chick", and is actually grammatically incorrect in that usage, as "hatching" is being used as an adjective to describe a fertilized egg instead of a verb. So, don't be too hard on people who assume the term means something else.
Much of today's English usage is grammatically incorrect, but adopted by the general populace, anyway. For example, people now commonly use the proper noun, golf, as a verb, "golfing". There's no such word. It would be like saying, "tennising" or "footballing". The correct verb here is "to play", and the proper noun, the name of the game, is "golf", as in "playing golf".
So, there you have the source of the misunderstanding by the uninitiated - the misuse of language.
I have just been guilty of "nerding" (see: "oh dear it appears I have nerded") and my autocorrect function has just crashed.
