Welcome to BYC.
This happened to someone else duck just the other day. The problem is birds hips are fairly strong and actually end up breaking before dislocating, in which surgical intervention or amputation would be required. A vet would be your best option here.
If you can't take her to a vet, you could try splinting the hip, but if it is indeed a hip fracture or dislocation the prognosis would be poor. If you want to give it a try you can read this link.

Something else I wanted to mention is the definite early signs of Bumblefoot on her footpads, as, at her age, there has to be some obvious incorrect management practices at play for it to be occurring this early.
I would be surprised if the rest of your flock
isn't showing cracking of the feet.
I saw a post in regard to splinting a limb. I haven't yet had to deal with that type of injury. I've dealt with niacin deficencies and a few underdeveloped chicks. If they continue to take food and water usually we can manage.
The local vets have expertise in cat, dog, and ruminants and not much experience with poultry or waterfowl.
I pulled the splinting manual and read over it, thank you for the resource.
I don't think I'm seeing bumble foot on this batch of ducks. (I've seen it prior in chickens, roosts were too high.) Our Peking-Rouen crosses tend to be mostly black with white acents and (upto) three color feet. Their foot patterns help us with early identification as their feathers change a bit as pass through four stages of plumage.
These ducks are in what I call a meatbird cage, it is a open bottomed hardware cloth sided moved daily. They are on grass (granted we are in a drought. (One inch of the average four has fallen this month and ground conditions are getting a bit rough until we get more rain.) They tend to create a manure pack where they sleep and a small mud hole extending around the 5 gallon waterer during the night. They are moved each morning around 9AM before I release the ducks (layers), guineas, and turkeys. The laying flocks free range over several acres. The meat birds will gain some more freedom once they are of a size that is cat proof; and won't escape the 2x4 wire.
I don't see any cracking, discharge, or scabbing from the foot. These birds are within the garden fence which is untouched by the other flocks (for about a year). The foot was in the waterer for a 0-12 hours. Do ducks get bathtub wrinkles on their feet? I think water for an extended period might be an irritant.
Now that I've dug up some 'pre-bumblefoot' pictures of duck feet; that is a maybe... Looks like I'll be making 11 ducks unhappy tomorrow by inverting them.
Butchered a few Guineas today; and making the comparison of musculature and bones. I still think it was out of joint. (Yes, I know guineas are a bit alien comparing them to waterfowl. It was their time; the flock needed balancing to reduce stress.)
Thanks for the information Isaac.
