Welcome to BYC!
Ducks need a secure run (with wire over top yes, to protect from aerial predators and climbers) and a secure house to go into at night. Predators will take ducks that aren't properly secured SO fast.
I think you'll be fine with just two ducks, the problem with ducks is having too many drakes to too few females (example: 3 drakes to 1 female would be a very bad situation for the female). Just keep an eye on him during breeding seasons that he isn't getting too rough with your other duck (provided she is a female; if you can post a video of them both "talking" we can sex them for you so you know what you have). Two boys together is fine, two girls is fine, a male and female together is also probably fine as well. More females is always best, but some drakes aren't as aggressive as others and will be fine and happy with just one female.
