"So you like ducks" what does this mean?

Here is the conversation:

A: I like software testing “QA”, it's my language

B: so you like ducks

Does A mean that B is like a sitting duck https://idioms.thefreedictionary.com/like+a+sitting+duck or is it something else? Is it insulting or positive or negative?


Appropriately, this site grew out of a site for computer programmers (of which I am not one, not even close).

It is a reference to rubber duck debugging

In software engineering, rubber duck debugging is a method of debugging code. The name is a reference to a story in the book The Pragmatic Programmer in which a programmer would carry around a rubber duck and debug their code by forcing themselves to explain it, line-by-line, to the duck.

It is not negative. Neutral to sharing a friendly joke.
