Hi All , My friend brought me a book on African greys for Xmas and have just got around to reading it today . Whilst reading the feeding section it said not to give your bird tap water for drinking . I have Gertie an 8 month old African Grey and have always given her fresh tap water daily ( refreshed several times a day ) and had previously done the same with my late grey Jack . Is this correct ? The book is mainly American based if that makes any difference . Your advice is needed please .
