The Cluck-ulator is the most comprehensive smartphone app developed for backyard chicken owners. The Cluck-ulator helps chicken keepers select breeds and manage their flocks. It's six tools in one: 1) The Breed Selector helps you choose a chicken breed based on characteristics such as breed type, egg color, temperament and more. 2) The Photo Gallery allows you to browse through a gallery of breed photos placed in alphabetical order. 3) The Coop Planner helps you build or buy a coop by determining the requirements based on your intended flock size. 4) The Egg Estimator tells you how many eggs you can expect your chickens to lay now and in the future. 5) The Food & Water Estimator - tells you how much food and water will be required to support your flock. 6) The Poultry Valve Calculator - determines the water pressure of your water supply tank based on the height of water in the tank.
