Comparing the competitive nature of roosters and hensFeatured science projectScience project video


The materials required for the experiment are as follows:

-    Three 1 month old roosters
-    Three 1 month hold 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 that is 3meters long and 0.3 meters thick
-    2 chicken cages
-    an assistant
-    a stop watch


1.    For this experiment, the independent variables are the chickens’ age and gender. The dependent variable is the amount of time the chickens take to reach their food. Use a stopwatch to time them. The constant (control variable) are the distance between the cage and the chicken feed.

2.    Use roosters and hens of 2 age groups: 1 month and 6 months. There should be 3 chickens from each age group. Fence an area that is 3m wide and 5m long. House the 12 chickens in 2 cages, according to their age. No food should be given to them 12h before the experiment.

3.    Test the 1 month old chickens first. Place the cage 4meters from a food tray filled with chicken feed. Time how long it takes for the chickens to reach the tray once the cage is opened. Calculate the average amount of time the 3 roosters and 3 hens take, and record this in the table below. Repeat the test with the 6 month old chickens.

4.    Repeat procedure number 3 the next day, but this time, first place a log between the cage and the tray.
