Bird Toon of the Day - September 27, 2017

We visit September 19 again, this time for Six Chix from last year. Which one is Heckle and which one is Jeckle?

(This toon originally appeared on the September 19 blog post, but when I saw that the toon I had held from that date for today was themed to that date, I went back there and swapped the toons out.)
