Abstract

240 newly hatched, mixed-sex broiler chicks were randomly allocated to 12 groups of 20. At 2 days of age, a group of 20 chicks was placed in the brood area of each of 2 T-mazes at 08:30 h; the brood areas were positioned on either side of maze. After acclimatization, one chick from each group was placed in the isolation chamber and the time it took to traverse the maze was recorded. This procedure was repeated until all 20 chicks and all 12 groups were tested. Testing was completed in the same day and two groups were tested at each of the following times: 09:00, 10:30, 12:00, 13:30, 15:00 and 16:30 h. Positioning of the brood area, test order, or time-of-day had no effect on behabiour. It is suggested that the future classification and possible selection of broiler chicks according to their T-maze responses are unlikely to be confounded by right-left preferences, test order or the time of day.
