Question: what is the meaning of ducks in a row?
Answer: get one's ducks in a row. Also, have one's ducks in a row. Complete one's preparations, become efficient and well organized, as in I'm trying to get my ducks in a row before I go to Europe. This synonym for get one's act together probably alludes to lining up target ducks in a shooting gallery. [ Slang; 1970s]
