Greetings ChickenNamedTaterTot,
Such a great looking rooster, a "Turken" or more commonly, a "Naked Neck".
He really should have a Veterinarian, take care of this. An x-ray would show whether or not this is fixable.
If a Vet is not an option, go for it. But, don't let him suffer.
Make a sling for the rooster. Put him in it to protect the break.

Then, splint the leg.
Here is an excellent video to help you.
Looks like it could be a dislocation and not a break. Either way, it needs to be addressed. The clock is ticking!

If there is no open wound, Preparation H applied to the adjacent areas, will help with any swelling.
Keep those hens away for at
least 48 hours, he needs to get healing. However, scar tissue is already developing.
Do your best, then provide a quite enviroment, and good supportive care. Which includes: cooked meat protein or cooked eggs, diced fruit, diced black or red grapes, fresh greens, cooked grains like: brown rice, wheat berries, oat groats, pearl barley, also some toast with butter is good. Always offer him moist and dry feed daily.
He should have soft foods while healing, at least a week or two.
If you have probiotics, give him some. Also, some poultry vitamins. Follow the product instructions.
Clean fresh water daily. I like to add some echinacea tea or aloe vera, to boost the immune system.
If it is really cold where you live, put him in the house, in a safe a room.
Keep him out of drafts and windy conditions till he is fully recovered.
These are my thoughts...I hope they are helpful.
God Bless!
