Not sure I want to get into this thread, but here goes. :hide:
IMO, it pays to keep your herd as uniform as possible, and sell in load lots if possible. The best selling lots of calves on sale day are always calves of the same color, sex, and weight, and enough to fill a tandem or triple pot.
My uncles used to pool calves together and many cattlemen still do in order to get larger numbers of uniform calves in the ring. My uncles bought Gelbvieh bulls from the same place and had similar preconditioning protcols.
Of course that won't work for everyone, but all of us can do what we can to present a uniform quality product in numbers on sale day.
I used to pull calves off in the fall and only keep what heifers I wanted for replacement. Toward the end of my carreer, I was selling the largest cut of steer calves off at weaning, and keeping everything else until I needed the cash flow. That usually meant I had some of the very latest steers left over as yearlings.
Then I would try to get a small but uniform group of calves together that would sell in one cut. Space and weight wise, my16' trailer bumper pull can haul about 14 - 500 lb calves. A few less if larger, more if smaller.
Kind of spread out the marketing risk, and I never had enough calves to sell in one cut for a semi load anyway.
