Version 1.27 has a new feature with chests - gathering behavior. We now can create fully automated egg farms. The flightless big birds are best suited for this idea. Plus, their cooked eggs are probably the most nutritional food in the game. Here is a picture of a working egg farm: To keep it simple, it's only 5 by 5 blocks inside. This keeps the water effect simple and only one water bucket is necessary. The walls may be any block. In the corner by the door, place your chest. Place one bucket of water in the corner opposite from the chest. NICE!
