Where in the world would I put a breeding box? How do I attach it to a cage? Is there a need to cut a hole in the cage to place it? Do I attach it inside? So many questions.

I don't intend to breed budgies just yet. I'm just curious about it all.

There's special breeding cages that have an extra 'door'. The box goes outside the door, with the hole facing the door. (no gaps) Leave the door open, and you have a breeding box. I know on a recent post someone made some links to some. Check out a few of the posts
