3. When we studied the cat, we found that she had four legs for walking and running, and that she used the paws on her front legs for scratching and catching her prey.
4. We have but two legs for walking or running, our fore legs being arms, and our paws, hands.
5. These new friends, the chickens, have but two legs, and in this way are more like boys and girls than are cats and dogs.
6. But the chicken has the same number of limbs as the others, only those in front are wings instead of fore legs or arms.
7. Here is a picture of the legs and feet of a hen. We see that the legs are covered with scales, and that each foot has four toes, three pointing forward and one back. Each toe has a long, sharp, and strong nail.
8. Let us look at the hen when she is walking slowly! As she lifts up each foot, her toes curl up, very much as our fingers do when we double them up to make a fist.
9. When the chicken is about a year old, a spur, hard like horn, begins to grow on the inside of each leg. Upon the old cocks these spurs are long and sharp, and he can strike savage blows with them.
10. It is when we look a hen in the face that we see how much it differs from all the animals we have studied before.
