Heres the 1.003 trigger (simple_triggers.txt). It's on line number 37 if you have a text editor that shows lines (like notepad2), or you can just search for some of the numbers and find the right spot.

There are many ways you could edit the way it works. The
red 0 and
100 are the parameters for the random number generated (between 0 and 100), and it then takes 0-2 for 0 cows (
3 in the code), 3-9 for big growth (
10 in the code), and 10-49 (
50) for negative
3-8. 50+ is the low growth one. You could change that to 45 100 to make it give a roughly 9% chance of
3-8 negative growth and 91% chance of small positive growth - that'd probably balance it out good enough to work, but it would remove the chance of big growth and big loss entirely. You could also go through and modify the
blue numbers - the first and third being the straight cattle added range, with the second being the range to subtract. The
lime green number (
3) is the chance of eradicating the herd. The
yellow numbers are the amount to increase the herd percentage wise, first for the big growth then for the small growth. It takes that number divided by 100 so 111 is 11% increase.
