HI there: Awsome choice parrots are beautiful! My dear they don't need anything as they do not in there natural enviornments! I have had cocketiels for years,the only time I needed them with something was if they were picking themselves,and most parrots do this out of being bored.
If you give them a good spray bath allow them to preen themselves and they are usually fine. And last there is a product called QUELL it is a spray which soothes irritated skin on birds. It's best used if birds are excessivly picking themselves!
I hope this helps I like birds more than people,the are the best pets in the world!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
