I have a few old cows in their teens, I must be getting old because I hate to haul the old girls to town.My numbers are way down,I got pasture for them,I believe Ill just leave them in the river pasture and let them be.Im not saying if things change I wont change my mind ,but these old girls have paid there way, and IM not sure a few hundred bucks a piece is worth hauling them in?..................good luck
