I bought some wood chews for my pigs. I'm not sure if I should give it to them, though, because I've heard they aren't a good brand. They are called Nutriphase Natural Nibblers. Small pieces of wood with bark on one side. Should it be okay for me to give to the pigs?

Also, if they are okay to give, what should I string them on? They come with holes drilled in the middle of each piece.

Thanks in advance for any suggestions.
