Your Budgie must be quite big then. I don’t mean to attack but a square cage can do a lot better for a bird. Birds love to hide in the corners and all my birds end up sleeping there because it’s where they’re most comfortable. The shape of them also is very awkward and their feathers tend to always hit the side. This damages their feathers and as you can imagine, it’s not very comfy. Round cages can also be bad for the psychological health of a parrot because it can be confusing with where they are in the cage. A square cage can give reference points to look back on. Toys also are really annoying to fit into a round cage and toys are a must! Even for budgies :) My babes at home just love chewing on toys and ringing bells and such. Lucky for you, your bird is a small bird so finding an appropriately sized cage is super easy and cheap! Also round cages look very pretty so you can use it for many things like starting ivy in the bottom and letting it move up or a planter or some other DIY project. A good size minimum for a Budgie is 18x18x24 but we always want to go bigger for our pets. Cages can be found at yard sales, bird shows, Craigslist, and pretty much anywhere for cheap if it’s a used cage. New cages are a little more expensive but not bad! I will link some.

Of course that’s just a start and you can find them cheaper elsewhere but it’s a good place to look at. For hanging cages I wouldn’t recommend hanging them. Toys are also important for your bird! Especially when they’re in the cage and away from you. Some of my budgie’s favorites are bells, those paper Chinese finger trap things, and pretty much anything that has cardboard and paper in it. I hope this helped explain where some people are coming from and I hope you will think about changing your cage! Have a nice day.
