Youngsters represented 12.3% of the animals gathered, consistent with a herd growth rate of seven percent per year.
Of the adults, 47.4% were male and 52.6% were female, no evidence of an abnormal sex ratio.
Body condition scores ranged from 3 to 5 on Day 29.

*According to advocates.
Day 29 ended with 6 unaccounted-for animals. The totals at the gather page balance, suggesting the numbers in the daily report are not accurate.
There are no plans to treat any of the captured mares with fertility control pesticides and return them to the range.

Overpopulation means more horses than allowed by plan, not necessarily more horses than the land can support.
The ability of the Complex to sustain wild horses has been limited by the bureaucrats, who have assigned most of their food to the public-lands ranchers.
