The incident began on August 2.  Gather stats through August 21:

The death rate is 0.4%.

Foals accounted for 18.2% of the horses gathered.  Of the adults, 42.7% were male and 57.3% were female.

Body condition scores were not reported.

Day 20 ended with 18 unaccounted-for animals.

The gap between males and females has increased.  The observed percentages cannot be produced by a random process centered at 50% males / 50% females with n = 1,219 adults.  The range of expected variation is found with basic statistical formulas.
