Facial blushing and feather fluffing are indicators of emotions in domestic fowl (Gallus gallus domesticus)

Caption

Domestic chickens were analyzed in different scenarios which evoked varied emotions and found to display facial redness (blushing) and facial feather fluffing. Happy, relaxed birds showed preening behaviors and facial feather fluffing. Happy, excited birds displayed slight blushing, while in fearfully excited birds, strong facial blushing was observed.
