Sometimes, I see my CAG with a nice black beak but other times it gets a lil grey! Is it necessary to clean you parrots beak? or is the shower enough to get that done? I mean i see some parrots with shinny shinny beaks, do parrot owners clean their parrots beaks with any special elements like lets say for instance, olive oil, or is that just a parrot who just had a nice sip of water?
