Yes, that spur needs to be taken care of. That can grow into the leg and cause a wound.
The way I take care of that is to use a Dremel tool with one of those discs you use to cut metal. A drill with a cutting disc would work too. I wrap the bird around the wings with a large towel or sheet and lay it down, always holding on to the foot.
The spur has a quick in it. That quick does not go all the way to the end but how close to the end can vary by the bird. If you cut the quick it can bleed so you might want to have some cornstarch or flour handy to stop the bleeding. I've nicked the quick a couple of times doing this and only had a drop or two of blood. I think the heat from the cutting disc cauterizes the wound. The rooster did not even flinch when I hit the quick, I don't think it hurt him. I try to take off no more than 1/4 of the spur length, that seems to miss the quick most times.
When I'm finished I just turn him loose back with the flock. He mates with a hen to let everybody know he is still the boss and life is good.
Some people on here use dog nail clippers, just taking the point off, not the whole spur. One lady said she uses a Dremel with a grinding head, starting grinding at the tip until she gets it ground down. I don't think that would work well on yours as I don't think you can get to the tip to start.
