Just like Kenny said. I have a friend that I do something simalar for. He's in his early 70s and has a small herd of cows but also likes messing with calves, there's lots of things he could buy and make better money on than the little knot heads, but he's not very interested in buying 6wt bulls to cut.
So about twice a year he tells me what he wants to spend on 10 calves big enough to wean. Couple months ago he said 750$ a head at about 200lbs, I got him 10 put together averaging 210lbs and added up to a average of something like 745$ a head for a mix of bulls and heifers. Lots of money for little stunted beef calves, but he will take care of them real good, sell them as 5wts in 6 months, make some money and be happy.
I guess what i'm getting at is, no matter how strange a deal like that is, if enough people start doing it, it will create a market for that particular thing, in this case it's the little poor doing calves that have became popular with certain people, enough people wanting them has made them cost more.
