Thank you for your help Kade! I totally agreeI'd suspect that your bird wants to roam around outside of the cage.
You've asked this question before
Active budgie
My female budgie (Bonnie) - (Mom) has been pacing left and right quite a bit. Does anyone know why?forums.avianavenue.com
My guess is that the cage is too small and has too many budgies in it. Typically, parents and their adult offspring will not want to share a living space unless they have plenty of space. You cannot offer the level of space without an aviary.
As @Ripshod suggested, share a photo or at least give the dimensions of the cage they're in.
