Colored clothespins help employees keep track of which calves have received which treatments. Depending on the calf, a pen might have up to three to four clothespins. The clothespins are spray-painted different colors to correspond with different treatments. Clothespins are initially positioned upright, and then flipped down when a treatment is actually administered. Calves are tethered to the front of the pens to prevent them from reaching the pins at the rear of the pens.
