I have a book about budgie care that was issued in 1980. They write I can give young budgies bread soaked in milk. However I've heard that birds can't digest milk. A couple of days ago a budgie breeder told me that he gives his birds bread and milk and they feel great. I've tried giving that to my budgie too and he's crazy about it now. Still, I'm uncertain if it's a right thing to do.

Do you give bread and milk to your budgie?
No. I still believe it's not their natural food so I avoid it. They are not mammals. Lots of human food is addictive too but it doesn't mean it is healthy.
