Does any one know of any bitter sprays that can be bought for birds chewing? I found one named Foiey and it is bird safe, non toxic and all natural, minus some preservatives. It has a money back guarantee. It tastes like the smell of nail polish remover. It is odorless and I don't believe Erin cares about the nasty taste. Se hasnt been preening as much but still does. I have tried mixing Listerine with water, too, but even as she smells good, that doesn't work too well and I am afraid that the alcohol in it will dry her skin, making er pick more. I heard some people mix mustard with water too, but this whole mixing mouthwashes and burger condiments seems absurd!
