Jed the Chicken

 

The animal shown in the comic is a side-striped jackal (Canis adustus). One was found in a duck pen eating the ducks’ mash, making no attempt to harm the ducks (Source: Canids: Foxes, Wolves, Jackals and Dogs - 2004 Status Survey and Conservation Action Plan).

The image in the comic is based on an illustration in Brehms Tierleben (English: Brehm’s Life of Animals) by Alfred Edmund Brehm (1829–1884) et al. (That book is available online at BioLib.de.)
