Link between chitin and cannibalism?

I just read an article on the crab street journal that claims that hermit crabs mostly cannibalize each other during molts is because of a deficiency of chitin in their diets and that they should be offered freeze dried or fresh shrimp/krill. I was wondering what other people thought of this. Also, as most people know, crabs are extremely social creatures with complex hierarchies and social networks with one another and im pretty sure they can even recognize all of their tank mates as individuals. Anyways, does anyone think that providing healthy amounts of chitin rich foods could eliminate the need for isolation? I mean, they live in colonies in the hundreds to thousands and they dont need to "isolate" in the wild.
