I have seen 'beak and feather' disease in cockatoos and I would like to know if it affects smaller birds like budgies?

yes

As lovey said, they do get it and it affects them in the same ways that it affects the larger parrots. It's such a horrible thing to deal with and one of the most contagious budgie diseases (if not, THE most contagious) out there. All pscittaicines (parrots) are able to contract PBFD.

How do you know if a budgie has the disease? Is it obvious at an early age?

 

I understand that large parrots can be quite old before they are declared free of this disease.

 

I should explain. I was chatting to the owner of a large bird store and I asked 'how much the correllas cost'. She said the 'babies were cheaper than the older birds, because the older birds were declared free of beak and feather disease'.

 

I was looking at the birds because I can remember my aunt having a corrella called Jack and she doted on him. He was just like her baby. But a very destructive one! I remember he chewed the plastic wheel off a lawn mower.
