I do agree that chickens are very smart. It only took ours one evening of being in the coop (we got our entire initial flock full grown from several sources) to know how to get in and out of the run and coop door to roost. They've also learned to see if we are carrying anything when we step out the back door so they know to come running for treats or not. Whenever I'm processing a deer they also come stand around the grinder because they know I'll toss them scraps that we don't eat and each and every time I open up our BSF bin they crowd around my feet waiting for yummy grubs. Now that I think about it chickens are very smart when it comes to food! I'd say they are close to being as smart as our dog and if I could train the chickens to fetch and guard the yard against cats and stray humans I wouldn't need the German Shepard.
Ducks on the other hand.... our ducks are dingbats.
