When I brought my bird home the breeder said to bathe her once per week via misting her. It quickly became clear she haaaaaaated when I intentionally bathed her. The only time she bathes is when it's on her terms and I leave the tap on at a slow dribble. She will go and bathe herself under the dribble very thoroughly, and she lets us know when she wants this by showing interest in the tap/sink. But usually she never does this more than a couple times per month, at most. She looks in great shape though. Very sleek and prim. So I figure that must be all she needs!
