There's alot to be learned by just simply observing what yer cows do. Hubby still laughs at me cuz I can load up my lil truck with a sack or two of cubes.....a couple cold dr peppers and just go out and sit amongst the cows for hours. But when it comes time to identify em...............who do they ask??? Lil ole me, cuz neither he nor his dad spend time out there like I do. I can tell ya by lookin at most of em, who there mama is, how many calves they've had, without ever lookin at their ear tag number or my record book.
