对四组蛋鸡的身体特征（体重、羽毛颜色、鸡冠大小和鸡冠颜色）进行了研究，作为社会地位（支配性、攻击性和社会互动性）的预测因素。在一组中，梳子颜色和优势之间存在显着的正相关。在第二组中，梳子大小和攻击性以及梳子大小和交互性呈显着正相关。在第三组中，体重和互动性之间存在显着的正相关性。在第四组中，没有发现任何测量的身体特征和社会地位之间存在显着相关性。所有群体之间缺乏相关证据表明，社会地位并不是由简单的形态特征决定的，而是涉及的机制更为复杂。
Physical characters (weight, feather co]our, comb size and comb colour) were investigated as predictors of social status (dominance, aggression and social interactiveness) in four groups of laying hens. In one group there was a significant positive correlation between comb colour and dominance. In a second group there were significant positive correlations comb size and aggression and comb size and interactiveness. In a third group there was a significant positive correlation between body weight and interactiveness. No significant correlations between any measured physical characters and social status were found in the fourth group. The lack of correlational evidence across all groups suggests that social status is not determined by simple morphological characteristics but that the mechanisms involved are more complex.
