Using Frozen Bottles of Water to Break a Broody Hen

In this video I successfully get my ISA Brown hen to stop sitting on eggs. She has been sitting for several weeks now and we have just been harvesting the eggs out from under her. That, however, has not broken her. My wife heard from Pinterest that frozen bottles of water works for breaking them from being broody. With a little trial and error I found that it does work.
I also provide a description of the ISA Brown chicken breed.
