Good points. With that in mind, I'll probably section part of the run off for the rabbits. Now to research and find some rabbits for sale.There are some that do that with their rabbits. I don't know that I would do it, though. The rabbits would be existing/living on top of chicken feces at all times(furry feet and soft foot pads do not do well in sticky manure and their noses would be so close to the ammonia of the combined urine of two species) and the two species aren't really similar in their living/eating/moving habits so I don't know for sure if it would be sustainable.
