My chickens go NUTS for corn on the cob. I have never tried hanging it, I just throw mine out there and watch as they take off with it and play "keep away".
I always buy lots when the farmers markets are up and running bc I can get it so cheap.
Any time we have a slightly bad cob in the summer, it goes over the fence. They run to it and the fight for it is on. Any left over goes to them. It is one of their favorite foods. Go for it!
