I like what you are trying…

I like what you are trying to do as a Whole

But from a farming back ground, i still cant see harvesting Calves, if you want your whole herd to grow . Down the road when the moose herd is more stable , a particle calf hunt
Its just not logical

Also I could not just see where you have stopped the hunter ( killer) that goes from group to group filling their tags for them, just because he can . That's not hunting
Example a Loger who knows where a herd is yarded up with several moose in it
