In a close-up, low-angle shot, three sheep are seen inside a pen, eating hay. The sheep vary in color: one is light brown, another is greyish-brown, and the third is black. They are standing close together, their heads lowered into the trough of hay. The pen is enclosed by metal bars, partially visible at the top of the frame. The ground is concrete.
