When my entire flock was killed by a raccoon but one we could not figure out how Blondie made it out of the attack alive bc she was running around the driveway when my wife found her and we have 9' fences around the entire run. That means she was able to in a panic fly to the top of 9' fence and jump or over the 9' fence w/out bothering to stop at the top. Oh yes she is a 14 week old Buff Orpington and they as you know is a large bodied hen. Surprised me how high she flew.
