Does anyone have experience with the Peckstone? If so, what do you think? I am concerned about if "natural beak conditioning" will hurt the chickens. I don't want to offer to my flock if it will harm their beaks. But, if it makes their beaks less sharp, without causing them pain/harm, it would certainly be beneficial for my hens that are low in the pecking order during weather times of more confinement. I was given one and have read up. They are usually used for large flocks that are more closely confined to reduce pecking injuries. Of course, this is because they are crammed together in factory farming situations, however, at the same time, if this does not hurt chickens; it is better than debeaking the chicken - which is something I would never do.
