Finches just laid eggs! Please help?

You can go to the pet shop and buy some nesting inside a box you hang on the cage and they pull it out making their own nest. If they just laid eggs leave them alone other then to feed and water them right now. They know what they are doing and if you leave them alone for a few months they will have babies for you. Like they are trying now. Just keep alot of fresh seed and millet spray out for them found at the pet shop too.
