They just turned one yesterday. The injuries started about 6 weeks ago when they were in the coop/run. I was hoping free ranging would help, but he has immediately gone back to her. I am going to separate him and see if that helps, but I am afraid rehoming him may be the only option.
That is still pretty young. The separation I'm suggesting would be for a very long time, essentially until fall to allow some maturity and hormones to pass. In sight and near the ladies where he can get a chance to practice some manners, tid bit to them, serenade, and practice his wing dance but not actually mount.
I have considered (and even bought one) a stag "tie out" like they use for cock fighting (forgive the reference) to attach them to their shelters.
Basically an upgraded dog leash that keeps a rowdy boy within a certain parameter and allows the ladies to approach or avoid him as THEY choose. Of course all considerations made for safety of the cock as well.
Those suggesting saddles and spur alterations could be helpful stop gaps.
I'll be honest.. I love and value a good (mature) head rooster but I
really enjoy hen only flocks so much more on a personal level. Although he's rough. selective, and maybe clumsy, If he is getting along with your other ladies and only this one is a problem.. re homing either one might be the easiest choice (regarding time and effort anyways). My heart is often *more* tied to those I worked extra hard to "save or comfort". Boys are harder to "home".
Only you know how much time, energy, and other resources YOU have to devote to rehabilitating.
Using craigslist farm and garden section, I can home most birds within 2-3 weeks max.
