I'm sure I haven't been the only victim to this issue. Is it possible to disable chickens hatching from eggs? Chickens have little use as it is and there are other ways to breed them.
That is a feature from Minecraft and not EMC so consider your request denied because I don't think JustinGuy could do that.
True although I think its harder then just install a plugin. All members of EMC would have to vote then JustinGuy would have to find the plugin then code it for CraftBukkit++ which is the type of bukkit that the server uses. I honestly think its too much work for the goal.
