Chicks, 8 days of age, were housed in a wind tunnel at temperatures from 12 to 28 C in increments of 4 C. The tunnel was equipped with a microswitch, an infrared bulb located above the switch, and a small electric fan controlled by a rheostat. Following learning, chicks were exposed at each temperature to air speeds of 0, .5, 1.0, and 1.5 m/s according to a Latin-square design. Chicks readily responded to air speed and temperature changes. For each increase of .1 m/s the effective environmental temperature dropped .6 C.
8日龄的小鸡被安置在风洞中，温度范围为12至28摄氏度，以4摄氏度为增量。风洞配备有一个微动开关、一个位于开关上方的红外线灯泡以及一个由变阻器控制的小型电风扇。在学习之后，根据拉丁方设计，在每个温度下，小鸡都要暴露于0、0.5、1.0和1.5米/秒的风速下。小鸡对风速和温度变化反应灵敏。风速每增加0.1米/秒，有效环境温度就会下降0.6摄氏度。
