Feeding chicken alone won't make it right. What you were feeding is the right way. Just because the dogs are in their 5th day doesn't mean they should be good. You need to go back to the drawing board and start from the beginning like how I showed you. If that doesn't work then your dogs are not meant to eat raw(bones). Pitbulls are not your average dogs. Their system, body, and mind are superior compare to most breeds. From what the owners of other breeds have told me, they are going through the same problem as you. I haven't had a pit that didn't like bones, so if I was you, I'd go back to kibbles and slowly add raw to their feed. Let their system get used to it first. Good luck.
