Numbers from various studies are obviously going to vary but no matter whose study you look at, natural mortality is fairly high and not many rams make it 10 years old.

I am starting to wonder if studies are worth the time and effort.
If you use 209's stats and start with 100 rams, by the time they reach age 10 you will only have one left if your lucky.
If you use Geist/SH's study you end up with 50 rams.
