Wow what an amazing artist you are! With two 4H shows under our belt we have learned to bath them with three tubs of warm water. The first has a few tbs of laundry soap, the second has a few squirts of human hair conditioner, and the third a tbs of white vinegar. Dunk in each in that order with some gentle scrubbing in the soap one. Don't get the eyes wet. Also use a nail file to shape and pretty up the beak and use dog nail clipper for for nails. Then at the show use baby wipes to tidy up and a light amount of baby oil or olive oil to shine feathers. Good luck!
