Hi. One of my friends decided it would be a good idea to spawn massive amounts of chickens from mob eggs to each of the player's houses on my server. I got rid of all the chickens at his house by nuking it repeatedly. But it's going to take forever to get rid of all of the rest of the chickens. I don't believe there is a kill all mobs command in vanilla servers, and I can't find a server mob that has this command. Please help!
