The easiest way to get this one is to be the monster. Set up a custom game to favor the monster and set the time limit to 5 minutes and then go hide in the corner and wait until the time runs out. The hunters will not be able to destroy all the eggs within 5 minutes. It doesn't matter what map you choose. Do this 25 times and the achievement is yours.
