The majority of fawns born this year are officially over the first major hurdle of their young lives; they have made through the first 2-3 weeks. Fawn mortality is highest during their first 2-3 weeks of life. Tiny newborns die at an alarming rate; they succumb to malnutrition, abandonment, disease and, most of all, predators. In high-predator areas, as few as 10 percent make it to fall. On average, about 70 percent make it.
