Abstract
This study was carried out on a poultry farm in the Department of Animal Production – College of Agriculture - University of Anbar, the experiment aimed to determine broiler chicks' undesired behavior, including fear, gathering, and isolation. Seventy-five unsexed chicks were used that belong to strain Ross 308 with the age of one day. Chicks were randomly distributed to five replications, each replicate contained 15 chicks. The fear behavior was studied by observing the situation in which the chicks of each repeater are present at different times of the day when observing the chicks, we counted the number of isolated chicks, that is, located at the corners of the field, and recorded them, considering that they were very afraid. Chicks that are a little far from the corner were considered Medium afraid, and those that are farther away from the corner are a little afraid. As for the chicks that are spread out, far from the corners and walls, they are considered natural and not afraid, this is what was applied to each repeater (color) and at each of the specified times to take Data per day during the trial period. The results showed significant differences between the treatments in each of the traits of fear, grouping, and isolation due to the natural stimulator (sound) to broiler chicks.
