Welcome. I agree with @Debbie292d that segregation works, but my experience is that this only works if one is not disabled. I have several handicap chickens. Only one do I let be with the flock, and I still have to keep an eye on her because of flock members that "go after her" because of her disability. Instinctively, chickens try to get rid of the "weak" members of the flock, seeing them as weakening the flock from predators. However, with our domestication of chickens and ducks, we do have some that are really good nurse mates. But the problem again is the instinctual one. I find with any animal, there are always triggers that will make them act instinctually, no matter the training.
Below is my favorite organization for disabled chickens/ducks. Please keep in mind that this rescue has full-time people dedicated to caring for the residents. You and I don't have this...still really great ideas.
