Ive tried all sorts to help get rid of them,she has a lovely new bath( never goes in )she prefers half an inch of water in her drinking bowl!! She has vitamins everyday,plus a spray from Northern Parrots recommended to soften the pins. We do a lot of head scritching which she loves,but other than that shes not bothered by them. She has a varied diet,I just wish she would use the proper bath!
