Like humans and other mammals, Chickens go through a REM (rapid eye movement) phase of sleep, which is associated with dreaming. However, they have another sleep phase that humans do not, known as USWS, in which one half of the brain sleeps while the other half is awake. Chickens can sleep with one eye open, an evolutionary adaptation that allows them to watch for predators as they sleep.
