Is it hard to raise elk?

I'm curious, could you elaborate on the difficulties associated with raising elk? Are there specific challenges in terms of their diet, habitat, or behavior that make them more difficult to care for compared to other domesticated animals? Do elk require specialized knowledge or expertise to ensure their health and well-being? Additionally, are there any legal or regulatory considerations that make raising elk more complex than raising other livestock? I'm genuinely interested in understanding the intricacies of elk husbandry and the potential challenges faced by those who undertake such an endeavor.
