I do have a book, it only covers keeping them as a pet, not working them. In that book it says ferret food is best but kitten food is acceptable if specialist ferret food is not available, which in my case it isnt unless i get it delivered. If kitten food is not ok, then i guess I'll have to do just that. Being a semi-regular shooter, i have killed rabbits before, and know how to gut, butcher an cook them so thats where they'll be going.
Thanks for the feedback
