Let's take a second to appreciate just how pure this is: Jessie Isabelle Price decided to use her brilliant brain to save ducks. This was no small accomplishment — her treatment saved the duck industry an estimated $250,000 during a time when farmers were losing about 30 percent of their water fowl each year because of disease. Thank you, Jessie. 🐤
