I've been feeding in my tubs for about 6 years now. Never had an impaction. I use aspen chips in my
Tubs. If they can process bone they can process a wood chip here or there. Since im sure in the wild they don't have special boxes they go into to eat, their digestive systems are
More than capable of handling plant fibers.
