What is the best way to defeat the zombie chickens in Plants vs. Zombies 2?

Those darn zombie chickens are a real pain in the butt! The best defense against them are the Spikeweed or Spikerock. The chickens will die when they run across them. You can also use the Lightning Reed's chain attack to kill multiple chickens at once.
