Kotowaza: Muddy the Tracks of a Standing Chicken?

Hum -- someone is having trouble with a computer that someone else used before, and didn't clean up. In talking about the problem, they fell back on this saying:
( Japanese behind the curtains . . .  )

Cover up the tracks of a standing chicken? Hide the tracks of the chicken?

Apparently a kotowaza about cleaning up after yourself, but I'm not sure how they got from the words to the implied meaning.　Sounds a bit like someone caught a chicken thief sometime by following the tracks, but that's a long stretch.
