Ok--went to the barn tonight to clean the horse stalls, and say Hi to my hens. My dogs bolted past me and were waiting impatiently at the barn door Tthe hens were walking all around the barn, and the dogs bolted right past them--basically pushed the hens out of the way and started eating all the poop off of the floor. Is there any harm in dogs eating this stuff? Other than the yuck factor--should I be discouraging this b/c it might be harmful? Just curious.....
