I'm writing a text about wells, some of them are dug by hand. On the internet I see many times the term "hand dug well" is used, but also "hand-dug well" and even "handdug well" are quite frequently used.
"hand dug well", "hand-dug well" or "handdug well", which one is correct?
(spelling correctors seem not to like the last one, so I suppose it must be one of the first two options)
