Where's the leg of my crow?

Before the program ended, one of my coworkers got into the office pretty much pissed of. Why I wondered.  Another coworker accused him that he has broken and stolen the leg of her crow and now she was threatening him with complaining to the manager. I was puzzled. What crow? Who has a crow? Was it a real crow? That's impossible! After the shock went by I found out that was about a small decorative crow my coworker had on her office for 14 years (wow, but why a crow?) and after she came back from her holiday she found it broken and with a missing leg. That upset her above everything and she waited until the people from the second shift came to point the finger at them. Nasty, mysterious case. Another Sherlock Holmes case? Or a new Agatha Christie novel? I'm being mean, but still, a crow? Come on?
