The New Chicken Feeder By RevanthDamerla
What I Wanted to Make • When I looked at the chickens, I saw that they got a large amount of their food from a special chicken feeder. I saw a lot of problems with the old feeder and wanted to change it to make it better for the chickens and make it easier for the workers as well.
The Problems • Food got wet • Food got dirty • Too much cleaning • Large mess and spillage around the feeder
What Are Chickens Like? • Will not eat themselves fat • Can’t fly well • Aggressive • Have the ability to learn • Learn best when they are young • Observant • Eat small-sized pellets and eat little food • Not smart??
Functional Requirements • Keeps food from getting wet • Feeds chickens when needed • Minimizes cleaning • Robust • Waterproof • Reloads automatically so people don’t have to watch it • Doesn’t use electricity • Works with chickens of all types, weights, and ages • Uses their possible stupidity
The First Design • Used gears to operate a lever to bring food out • Stored in a large tower • Automatic reloading • No electricity • Easy to use

Analysis Does the Spring Stretch Out? Watch the Chickens F=kx 5.5 lbs=1.57 lbs/inch(x) x=3.5 inches
Testing!! What it Looked Like The Results Began the integration process to teach the chickens that the box and going up the lever means food. Chickens are getting used to the lever going down as they walk up. They have figured out where the food comes out
What I Would Change • Not waste as much space by creating a more efficient funneling system • Make a better system to get the chickens out • Stores more food so it will last longer without humans needing to operate it
What I Learned • Engineering Design Process • Use your notebook and label properly. Make sure everyone can understand everything. • Occam’s Razor • Saint-Venant’s Principle • Abbe’s Principle • Leadscrews • Different types of linkages • Think of possible problems before building.
