Egg problem! (budgies)???????

This has happened to me. You need to leave all sorts of materials around the cage OUTSIDE OF THE NEST VOX and let her pick for herself what she wants in there. I would put the orange thing in the nest box, but on the side, so she can choose if she wants it or not. Basically a bowl shape helps bone formation, but she will likely do that herself. People market things that people think make sense, but don't care about if its really good for the bird. put both hard things like big beads and soft things around the cage for her to pick up.
