I'm not sure if palm oil is all that good for parrots. i did a look around the internet and found a number of articles that did not advise it.
also, I wouldn't ever use those products that you purchase in a bottle to spray on birds, like AviRain, etc. because it just means more chemicals that the bird doesnt need. a
another REALLY important reason never to use a spray product as a bird bath is because if there's a chemical in there that has a particular taste that the bird is fond of, it could start a plucking problem overnight. so i would steer clear and avoid bath spray products like that.
birds have their own preen gland oil that moisturizes their feathers. pure water, the best quality available (filtered,etc) is best for your birds bath. and a bath in a dish is perfectly fine if your bird doesnt like to get misted. my GCC hates getting misted, but will come running if he hears or sees water anywhere, because he loves baths in a bowl or from a tap.
so see what your bird likes best, and go with that. if he likes a bath in a dish, thats great.
a lot of birds molt a little bit throguhout the year. thats what my GCC does.
i hope that helps!
