Hi there and welcome to the forums!
It is very important that you get a new cage for your budgies as soon as possible. Rust is highly toxic to budgies and even if they eat a little it can be fatal.
Please get a new cage as soon as possible and be sure it is large enough for the number of budgies you have. I’m not sure what the conditions are in your country for budgies sold as pets but please do your best to care for them according to best practices for the sake of their health and happiness.
Appropriate cage sizes and setup info can be found here:

Best wishes!
