Facts About Chicken Sleep
Chickens sleep similarly to other birds, exhibiting rapid eye movement (REM) for short periods each time, which indicates that they are in a dreaming state. Interestingly, while humans experience REM sleep that lasts longer—ranging from a few minutes to an hour—chickens undergo a unique sleep stage known as unihemispheric slow-wave sleep. This type of sleep allows one hemisphere of the chicken’s brain to rest while the other remains alert. Consequently, it is not uncommon to see a chicken sleeping with one eye open and the other closed. This behavior is a natural defensive strategy, enabling chickens to remain vigilant against potential predators even while feeling drowsy.
Insights and Facts About Chickens
Here are some intriguing facts related to chickens:
- Chickens possess a remarkable memory that rivals that of elephants, and they can recognize up to 100 faces of their fellow species.
- Chickens have the ability to distinguish colors just as well as humans do.
- They communicate using over 24 distinct sounds, whether it’s to share observations, warn about predators, or express discomfort.
- Chickens have pain receptors in their bodies, allowing them to feel distress and pain, especially when suffering from injuries like beak trimming.
- Mother hens display courage when defending their chicks against threats from predators.

- Roosters perform a distinct dance to attract hens by bobbing their heads up and down, and hens are more attracted to roosters that are surrounded by larger groups.
- Hens communicate with their unhatched chicks, who respond with chirps from within their shells.
