Chickens I had that free ranged the furthest were very capable fliers making them very difficult to catch for critters like foxes and coyotes. Upon detecting the predator the chickens would stop feeding and compress their feathers to take on a more slinky dinosaur look. They would also give low intensity alarm calls intended for flock mates only. If predator closed in, then the birds would start running for cover (trees or barn) and as predator got close close an alarm is produced only when exploding into flight. Some fly for trees where they can land >20 feet up. Others will fly the entire distance back to protection of barn they will land in paddocks or on roof of barn. Dogs milling around barn then would be in position to deal with predator.
I used to slowly drive flocks of game chickens to the edge of where they free-ranged to see sequence used to escape me. Flight speeds I think exceeded 35 mph pretty easy. Most other chicken breeds likely do not have this capacity. Leghorns do not have the smarts or endurance needed.
