Budgerigar can't fly, and can't even stand on a wooden pole. What should I do?

A congenital disability that cannot be cured.

The reason is that there is too little sawdust in the breeding box or it is squeezed by other chicks and cannot be cured.

Third, lack of nutrition, you can add more nutrition to food. For things within the scope of vitamins, you can try "electrolytic multivitamin". As long as you supplement the follow-up nutrition, you will stand up slowly.

I hope I can help you.
