ya, even with a large herd....I get one taken from me every now and again. I find the hides and meat, sometimes the saddles I put on them. I keep 4 saddled in a few locations surrounding my Plains compound to allow for a good chunk of Riding XP...when one critter's Stamina gets depleted, I jump on another one nearby with a saddle.

I've got ~8-10 on the Plains outside the base, 6-8 in my taming pit, another 4-5 in the Meadow behind the Plains base, in view, and about another 10 in a walled enclosure in the Meadow just beyond the grazing herd there, so quite a few Lox tamed and grazing nearby.

You definitely have to tend the herd with cloudberries from time to time...or you will begin to lose more than a few quickly; it also keeps them happy and breeding so it pays to tend your herds of tamed Lox.
