The productivity and welfare of broilers chicks was examined when hens calls were played at the feeder. Fifty-two chicks were housed in 16 pens. For three minutes every hour, 8 of the broiler pens heard hen feeding calls, while the control pens were not played any vocalizations. The experiment ended on the 9th day of age. However, the feed intake and growth was measured on 17, 24, 31 and 38 days of age and the carcass yield was measured when the broilers were 40 days old. During the experiment, the chicks that received the hen’s vocalizations had improved feed conversion ratios and weighed more. When the chicks were observed on 1, 4 and 7 days of age, the chicks that heard the hen vocalizations situated themselves significantly closer to the speaker than the chicks not hearing hen vocalizations. The behaviour of the chicks suggests that they are attracted to the sound of the hens vocalizations, as they remain relatively close to the speaker. There was not a difference between the two treatments, once the hen vocalizations ceased, in terms of body weight, feed efficiency and carcass yield. Therefore, the advantages obtained from the playback of hen vocalizations up to the ninth day of age where not evident once the playbacks ended. This study has proven that playing hen vocalizations to chicks is benefits the productivity (increased body weight and improved feed efficiency) of chicks during the first nine days of production.
