I've just had 2 young finches for 3 weeks, ages 6 and 7 months, and I'm concerned they already may be trying to mate.

I am absolutely, positively NOT ready for this. At all. I've not yet even had time to adjust to my new bird-keeping responsibilities -- now the prospect of potential babies is truly scaring me! In fact I haven't even decided if I want to breed them at all, and purposely have not provided a nest. If I do choose to -- at some point -- it will be at least a year away before I can even consider adding that to my agenda.
Here's what happened this evening....maybe someone more experienced with Gouldians can tell me if it's anything to be concerned about:
I just happened to be watching when this behavior occurred. They were sitting on a branch within a couple inches of each other, and I had just noticed each of them nibbling at the plastic/silk vines and leaves I've attached to the roof of the cage. (A whole other concern -- I've never seen either of them do this before, except for a brief moment yesterday when the male did.)
Suddenly the male lowered his head toward his feet and began violently shaking his head back and forth for a minute or two. At first I was concerned he had poisoned himself by ingesting something toxic from the fake leaves! But then he raised his head and began hopping up and down on the branch -- as I've seen Gouldians do in videos....best I recall, it serves as the male's signal to "Let's get a room."

After a few moments, the hopping stopped, and the lowered head-shaking resumed, then he was hopping again. This alternated for about 6-7 minutes. At some point the hen also lowered her head and began quickly shaking it in the same way. Even my opening the cage door to wave my hand nearby failed to stop them -- it was if they were in a trance, or possessed!!
Then the male flew to the other side of the cage and began searching around (for a nest?). The hen then began obsessively nibbling at the fake leaves again, non-stop for about 10 minutes. I tried to stop her, but she would just find another leaf.
Is this indeed mating behavior? At such a young age?? They are barely the equivalent of teenagers! Short of separating them (not practical), is there any way to stop this behavior? Why is it I suddenly feel that my birds need an adult chaperone 24/7?
