Justin, what numbers of calves are we talking about at the prices you mention? Pot loads, individual sales for a home freezer, or something in between?
What age and feed, such as grass only, or what level and what grain if grain fed?
How are they marketed, through local sale rings, ads, other?
Probably most of us could qualify as "natural", if not organic, but jumping through the ' hoops', plus the liability of someone finding a problem we did cause and did not know about might take the 'profit' out of the deal pretty fast, IMO.
