If you are planning to keep captured foes in order to try an convert them, it may be a good a idea to expand your hatchery. In order to heal up your prisoners ready for torture, you need to feed them an awful lot of chickens, especially Barbarians, Giants, Lords and Ninjas, who eat tons. If all your chickens are going to your prisoners, there are none for your own monsters! They will get hungry and angry because they are not being fed. So expand your hatchery quickly.

Why run twice, when once is enough?
