The question here should be are you truly ready to breed your budgies?
The decision to breed comes with a whole lot of responsibility and commitment, the lives of the breeding pair(s) and the chicks are depending on you and the response you give if/when faced with adversity.
Things like being able to tell if your breeding pair is in good health and top physical condition to go through breeding; when a hen is expecting an egg or if she is showing the first signs of being egg bound; when a chick is having developmental problems, not being fed or showing signs of dehydration;
when there is aggression, abandonment and neglect of the chicks and it's solely up to you to feed and raise the chicks. The ability to detect early on and solve these issues can truly make a difference on the outcome of your breeding journey.

Budgies need to be properly conditioned and on adequate breeding diet before being set up to breed. If you have only witnessed a sporadic mating, this doesn't mean that eggs will soon follow. If you are not yet completely ready, it would be best to remove the nest box and take the necessary measures to discourage further breeding behaviour: https://talkbudgies.com/budgie-breedi...want-eggs.html
Also for your budgies' overall welfare and safety it would be best if you replaced that rope perch for a new one, since it's already quite frayed.
