Sorry about your chicken! Poor girl! I would try lots of peanut butter to get the sticky off, then Dawn dish soap to get the peanut butter off. I bought a sticky fly thing last week to control the little fruit flies in my kitchen. I tried to hang it, but it fell, and I caught it. Really caught it-that thing was beyond sticky. Then I touched my glasses. What a mess! It is working on the flies though. Good luck cleaning up your chicken, and that was really smart thinking to use cornstarch to cut the stickiness.
