Inside duck

[Brick Chick]

I just ordered a diaper for my duck. I have only one duck. Do they do ok as an "only child" I also have a dog. They get along very well. My duck is 10 weeks old and has lived outside until now. I have lots of questions about moving my duck inside:
Where does it sleep?
How often should it go out?
What do you do about feeding... keep that outside?
Tell me everything I should know about having an inside duck.
This is a male Khaki Campbell and he is super sweet so I am excited about him moving inside!!
Any tips I need to know about the diaper??

If I had a female (which I don't) where would it lay it's eggs? Would it be able to lay eggs with a diaper on??

Thanks for all the advice!!
