How bad is it in Jenkins state prison. With all the fighting with inmates

It is not better or worse than any other prison. Fights happen in all prisons and jails. The inmates that get into fights are the same type personalities that get into fights outside of prison. If your inmate wants to steer clear of fighting, they should learn about the "rules of respect" - not interrupting others, don't butt in line, don't reach over another's plate, don't be a snitch, don't be in other's business, don't listen in on other's conversation, don't change the TV channel without asking others that are sitting there watching... pretty simple rules to follow to keep their coconut from getting cracked.
