Dried sweet corn as a chicken toy

We still have one hen in a tractor, destined for the pot once we get a pause in our busy autumn schedule.  As a sop to my conscience, which doesn't feel bad about eating her but does feel bad about putting her in solitary confinement beforehand, I like to give our loner treats.  Her current favorite is dried sweet corn, hung by its dried husk through the top of the chicken tractor without securing it in any way.

Our loner hen picks a kernel at a time off the cob and it takes her quite a while to make it through the ear of corn.  I suspect that urban chicken-keepers could use a combination of dried sweet corn and sunflower heads to keep their chickens occupied, a bit like inside dogs are often left with those peanut butter-filled chew toys when their masters have to be gone all day.  Add in our homemade chicken waterer and you have a recipe for active, healthy chickens rather than a picked and pecked on flock.
