The daily reports indicate 183 horses captured through January 17, with no foals.
Is that what you’d expect for a herd that’s growing at a rate of 20% per year?
No, you’d expect to find 153 adults and 30 foals, although it is a bit early in the season.
A simple model for population growth would be 100 adults last year plus 20 foals this year, so the youngsters would represent 16.7% of the herd (20 out of 120).
