Awesome!
The reason I asked was that I had someone who surrendered a duck to me and said that after she tried to pick the spots off, she tried to scrub the spots off with bleach, thinking they were mold from the water. 
Luckily the duck made a full recovery.
Some people, I had a guy at our feed store tell me to put bleach in their drinking water to worm.
