That's kind of funny. They do like to escape when ever they get a chance.Brat! I knew they were occasionally escaping, but I didn't think they were flying over the 6' fence. There's not much take off room, so it's almost straight up. I know they can fly, but I didn't think a 9 week old could get that much height without more take off room. Rescued one from a cockerel this morning. The chicken was standing on him with both feet and pecking the snot out of him. The cockerel never saw me coming. He went for an unscheduled flight as well. I didn't hurt him, but he was surprised. I guess I'll be extending the fence to the roof.
I have had to use some 12" chicken wire around the tops of some pens to close up the gaps here to.
