How do I integrate my newest duck into my small flock??

So, I had 3 ducks. A drake and 2 hens. I managed to successfully hatch 1 of 7 eggs and had to raise the lonely duckling in my house.
When she was small my Drake constantly tried to kill her, now he's always trying to mate, which is horrifying to my baby girl. She's always on the run when she's out with them and daddy drake does not tire. (I've been keeping him in the coop while I'm at work)
Her mother and aunty duck are scared of her, and it's all just chaos.
Anyone have experience with this? Will they eventually learn they're all ducks and get along?

Also, she's almost 2 months old and sounds the same as she did last month. Maybe she's a drake?

Whether she's a drake or not (and that is a possibility) she should be kept separate from the adult drake. I'd remove him from the flock and integrate her and the two adult hens. I'd try reintegrating the older drake in late autumn .

Thank you! I'll keep baby duck away from my drake for a few more months. No need to rush anything.
