Emotion can also cause chickens to get red in the face - EurekAlert
<p><strong>How can we know what chickens are feeling? An INRAE research team were able to uncover various degrees of redness on chickens' faces depending on their emotional state, while, at the same time, demonstrating that the skin of chickens that were used to humans stayed lighter in colour, thereby indicating a calmer state when humans were nearby. These results, which provide keys for assessing animal welfare, were published on 21 April in the <em>Applied Animal Behaviour Science</em> journal.</strong></p>
