A simple procedure for testing newly hatched chicks' responses to olfactory stimuli is described. Chicks that were hand held under a heatlamp became inactive and closed their eyes (as if asleep) within 2 min. Sleeping chicks displayed overt behavioral responses to an odorized q-tip (head shaking, beak clapping) that were not observed in awake chicks. Sleeping latencies were shorter for 1-day-old chicks that had been food deprived prior to testing than for chicks that had ad lib access to food and water. When airborne odors were presented by squeezing a soft plastic odor bottle near the beak, sleeping chicks' reactions to mint were of a greater magnitude than their responses to lavender or orange scents. Nonetheless, all three odors elicited more pronounced behavioral responses than did the water control stimulus. This method allows rapid testing of individual chicks for odor detection and discrimination.
本文描述了一种测试新孵化小鸡对嗅觉刺激反应的简单程序。在加热灯下手持的小鸡在2分钟内变得不活跃并闭上眼睛（好像睡着了）。睡眠中的小鸡对带有气味的棉签表现出明显的行为反应（摇头、拍喙），而清醒的小鸡则没有观察到这些反应。与可以自由获取食物和水的小鸡相比，在测试前被剥夺食物的1日龄小鸡的睡眠潜伏期更短。当通过在喙附近挤压软塑料气味瓶来呈现空气中的气味时，睡眠中的小鸡对薄荷的反应比对薰衣草或橙子气味的反应更强烈。尽管如此，所有三种气味引发的行为反应都比水对照刺激更明显。这种方法可以快速测试个体小鸡的气味检测和辨别能力。
