Zoology Science Fair Project

Roosters vs. Hens

Roosters vs. Hens | Science Fair Projects | STEM Projects
In this experiment, we'll compare the competitive nature of roosters and hens. We'll measure how long it takes for them to reach a food tray, with and without an obstacle.


The hypothesis is that the roosters will get to the feeding tray faster than the hens.

Method & Materials

You will need three 1 month old roosters, three 1 month old hens, three 6 months old roosters, three 6 months old hens, a bag of chicken feed, an area that is fenced, a feeding tray, a log, two chicken cages, an assistant, and a stopwatch.
You will measure how long it takes for the chickens to reach their food. The distance between the cage and the chicken feed will remain constant.


The results showed that the roosters reached the food tray sooner than the hens. The 6 month old roosters and hens were also faster than the 1 month old chickens.

Why do this project?

This science project is interesting because it compares the competitive nature of roosters and hens. It also shows how domestication of chickens has changed over time.

Also Consider

Consider testing ducks or turkeys instead of chickens. The experiment can also be repeated to compare chickens of different ages.
