My husband approaches cattle ranching completely different than anyone I have ever known.
He is out choosing which cattle will go to market. Now, let me mention all our cattle are the same color and sometimes that makes it difficult to tell them apart especially if they have lost their tags. The cows do have names like Bob and Big Teats so he can tell them apart. I guess moving in a herd, it is more difficult to pick out Kim from all the other similarly colored ladies.
Hubby's solution...paint gun balls! He is out shooting his cattle with bright yellow paint balls so he can cut them out easier come sale day...gotta love him. I am sure his cattle do. Although they didn't seem to mind, just a flinch and they kept on grazing.
