Since you think it's wrong to slaughter animals for meat or fur/hides, what do you intend to do with your calves and lambs?
Before going any further in your quest for a farm, you have to sit down and do some serious soul searching. Decide which markets would best suit your goals/ideals. It's easier to be a success at something if you have a plan. Nobody plans to fail, they just fail to plan.
Even if you decide to raise future breeding stock in your chosen species, you have to realize that not every animal born is worthy of passing on it's genetics, and those animals have to be culled.
