I compared the different models and prices and eventually chose a medium-sized cage from the brand Tallinn:
|Blue Tallinn budgie cage with supplies.|
- It only has horizontal bars (which is easier for budgies to climb in)
- The cage itself is also horizontally shaped, which means that budgies can fly around a little bit (this works better than with a vertically shaped cage)
The price of the cage was 70 EUR, which is reasonable, as it came together with a bunch of cage supplies (eating and drinking tray, sitting perches, even a nice-looking toy).
Remember that even a large cage is too small if your budgies have to live there constantly. That's why it's important to give them enough hours of free flight during the day.
