At the county fair, my girls' poultry leader was gushing over HRH Princess Bonnet von Hathat's (real, registered name, BTW) snowy white crest, and she asked my DD what she used to wash her crest with. DD said "Plain 'ol Ivory soap. What do you use?" The leader went on to say how she used all these different hairdressing chemicals to get her flock's crest as white as possible, different brands of expensive shampoo, and assorted other stuff I can't remember. In DD's defense, her head wasn't that dirty- if you have a filthy crest, do you use something a bit stronger? Which brings me to my question- What do YOU use to wash your Polish heads with?
