The can sleep having one eye open and one eye closed or both eyes closed. It depends on where they are. In a group, usually the other chicken will keep its outside eye open to watch for danger while the other eye sleeps. The inner chickens will sleep having both eyes closed. Each eye is controlled by a different hemisphere of the brain. Ducks do the same thing.
Yes they sleep with their eyes open :)
No. Kookaburras are not known to sleep with their eyes open.
Cats Sleep in nests and small hollows they find.
No. They close their eyes like us when they sleep.
Sometimes, yes. I have seen a cat sleep with his eyes open before. It's probably how they keep an eye on their surroundings while they sleep.
