Alright. I set up an automatic chicken farm. Basically what it did was have transposers sucking up eggs, tubing them back to a deployer, and having the deployer shoot them at a block above the pen. I let this run over night and it got a bit out of hand. By the morning, the number of chickens had grown so much, they had gotten me from 50 FPS to 1 FPS. I then decided it was a good idea to put lava in the pen to kill all the chickens. At this time, I had completely forgotten that fences can burn *facepalm*. I left for school, and when I came back, I found that all the chickens had escaped and spread out over the whole area. I need help on how to kill them without having to manually go up to each chicken and hit it with a sword. HELP!
