Dogs can have small amounts of blood in their poop from a variety of things. This sounds like it’s probably a sensitivity to chicken or a switch in the diet. Dogs with sensitive systems can have these symptoms too.
If you’re still wanting to go the raw route perhaps try to slowly mix a premade raw food (nature’s variety, primal, Stella and chewy) and see how that goes. Transition the same way you would with a new kibble. Over the course of several weeks.
There may also be an under lying problem. The answers was a cooked plain broth so I’m not sure why that would cause any upset. I would go to the vet and mention it to them. I would first mention the answers and see what they say. Then perhaps mention the raw chicken later. Traditional vets will immediately jump the gun and blame it on raw as they are trained to support large kibble companies only and that may bring them to a wrong conclusion when something else may actually be going on.
