Clipping a chicken's wings prevents it from flying out of its pen. It is a simple and pain-free process. It can be done by one person, but it's easier with two (one to hold the chicken and the other to clip the wing. In this instance, I both held the chicken and clipped the wings because I needed a camera person.)
Supplies: Scissors
First (and most fun), catch the chicken.
Once you have the chicken in your arms, spread it's wing.
