1 Determine how much fence you need. Mark off the area for your fence with small wooden stakes. Measure the distance between the stakes. Add the measurements together. This is the length of your fence. If the length of your fencing is not evenly divisible by 5, add on extra feet until it is. 2 Determine how many stakes you need to build your fence. Take the length of your fence and divide by 5. This is the number of chicken wire stakes you need. 3 Tie a string from one wooden stake to the next, connecting them all. The string serves as a guide for setting the chicken wire stakes. 4 Begin with the corners. Using the sledge hammer, pound the chicken wire stakes into the ground until the metal flange at the bottom of the stake has been driven completely underground. Once the corners are set, place a stake every five feet between them. 5 Pry the metal hooks on the chicken wire stakes open with a screwdriver. 6 Hook the wire of the fencing into the stake hooks, making sure the bottom of the chicken wire is flush with the ground to keep animals from going underneath it. 7 Close the hook around the chicken wire, binding it to the stake. To do this, hold the sledge hammer behind the stake and pound the hook shut with a regular hammer. 8 Use the tent stakes to hold the chicken wire to the ground, hooking them through the wire and pounding them firmly into the soil.
