Hi, Tyler! Welcome to TB!
I would agree with Deb. First, I think it would be better for you to get to know your budgies before you breed them, not only for the reasons stated above, but also because they need to be comfortable with you so you can interfere if something goes wrong with the clutch, and so you can be part of their "flock". Bonding is important in breeding because that way, they won't get stressed out when you're near, which could impact any babies as well as the parents.
Also, I'd like to add that you should be sure the next box is clean if and when you decide to use it!
And another thing
Although it's entirely up to you whether or not you decide to clip the bird's wings, I would not clip them because as aluz said, that does not make them any more tame any faster. In my opinion, it is better to let their wings grow out and move their cage to a small room where you can let them out to fly for a few hours every day, and being in the room with them will help facilitate taming.
It seems the two are already becoming best friends, that is why they tend to do things together!
I can't wait to see pictures and please keep us updated on how your darling little budgies are doing
Please don't be afraid to ask about anything you're unsure of
