Easy to accomplish. The first appearance of the phrase was in a 1902 newspaper cartoon that had nothing to do with ducks. Not then and not now has anybody been able to suggest a likely derivation. If you're interested in an expression that makes sense, try the equivalent, “as easy as falling off a log.”
