A common mistake is not electrifying it. If the fence is not properly energized (minimum of 3,000 volts), animals may escape or become entangled. On a % basis, entanglement is very rare, but it can and does occur. If animals are scared or starved it will not keep them in. The first time you put the animals in the net, you should be available to watch them for a while. That way if one were to get into the fence and get caught, you can turn the power off and get them loose.
