Alligators are archosaurs.
All birds, including chickens, are feathered theropod dinosaurs, which are a type of archosaur.
So it's more correct to say that alligators hang out in trees because they are just big four-legged chickens.
They definitely do. My mom raised chickens free range for a while. They spent large parts of the day roosted in her cedar tree. They can't fly very high, but they can get enough lift to catch low hanging branches and climb up from there.
