Hi.
Leave them contained for 72 hours so they know this is their new home? Not even sure if they can fly.
Do keep them enclosed for 3 to 7 days, so they can get used to the fact
this is their new home.
And since they are
new,
whatever their breeds are :
do clip one of their wing.
I have indeed learned
even the biggest of the ducks actually can fly; so, clipping the wings of your new birds will prevent them to fly away - and probably, thus,
save their life.
(If ever they fly away, they could easily get lost, and so : be
unable to get back home!!)
Breeds that size won’t be able to fly.
They generally do
not, but they actually
can fly.
(There are some videos on
Youtube.)
Even Indian Runners, that are literally renowed - and chosen by a lot of people
for - to not be able to fly, are actually able to...!
So, just in case :
I would clip one wing of each duck here... at least for the first year!
They may be able to fly short distances at most.
Ah, ah!
(Big) ducks are amazing!!

Just for
that... I would be kind of scared of the ducks flying away!!
(We never know, right?)
Wouldn't the roosters prevent the drake from trying to breed with them?
No.
From
my experiences, a rooster won't protect his girls from a
rapist drake.
I think there are two reasons to that (noting here I may not be right) :
1 - roosters don't consider drakes as (romantic) rivals, since drakes are
unable to have offsprings with chicken hens;
2 - drakes are not
predators (as foxes or raccoons are, for example), so roosters don't feel their girls' life
is threatened by them - even though a drake
can still hurt, and even
kill, a chicken hen by raping her
(but a rooster does NOT know that, apparently!).
...Nevertheless, you
probably don't need to worry about your drake assaulting your chickens for the time being.
Monitor them closely, but you should be fine until next mating season... and
even then, you could be lucky AND your drake might not try to mate with the chickens...(?)
I am to the point of just letting the ducks stay on the pond.
Don't.
You don't want your ducks to be eaten by nocturnal predators, right?
