Not to mention the fact that chickens are some of the most appreciative creatures on earth. As I boy, I remember taking them not only table scraps but some things that were pretty gross, rancid, sour and rotten.
They flocked around the feeder and enthusiastically ate as if you'd just served them a gourmet meal.
Idk about appreciative, but I know that chickens really are stupid creatures. Birdbrains you might say.
