My girls absolutely love hay bales. I have a shelf on the back of the coop where I put bales to keep them dry and out of the weather. Once I take hay out of a bale I stand it on end propped against the roof to keep the girls from using it as a nest. Well I came out to the run the other afternoon and one of the girls had managed to scratch out the side of a half bale causing most of it to fall into the run where it was promptly scattered similar to kids jumping in a pile of leaves. Meanwhile all of my hens are standing there with the "I didn't do it" look. If you want to see chickens in their glory then give them a bale of hay to demolish.
