Yes and no to the overdosing question. There are two different types of vitamin- water soluable which the body cannot store so any excess just gets passed out as waste and fat soluable vitamins which get stored by the body for future use.
If the vitamin in question is water soluable then you cannot get too much of it as what the body doesn't need is just passed out in urine/faeces, obviously in birds it will just get passed out in the poop in 1 go. (B1, B2, B3, Pantothenic acid, Biotin, B6, Folic acid, B12, vit C)
The fat soluable vitamins can cause problems if too much is stored, just the same as having to much iron in your body can cause problems- irons needed but in small amounts. Having too much can be as dangerous as having too little. (Vit A, D, E and K)
Something else to bare in mind is that the body makes certain vitamins in certain circumstances -Vit D for example and exact requirements for our parrots are not known so I feel it is too easy to get it wrong.
My personal opinion is that I would only choose to supplement the diet with vitamins if the bird had already proven to be low on something via vet tests and if the vet told me to give one.
Also please note: that birds are not mammals and the information I have just given was researched as part of my course for mammals. Birds may differ (I doubt it but havent looked into it) in how the vitamin are processed so its best to research on an individual basis and don't just take my word for it.
