Escaping chicken!

We have three lovely ordinary brown hens, a year old now and laying eggs with alarming regularity! They have very distinct characters, Mrs Weasley is a quietly confident hen - always trying to steal food from our black Labrador! Ginny (Weasley) is happy in the bushes looking for slugs, and Bingo is the bold and adventurous one!
The three ladies live in a converted play house with a run around it, and are allowed out into the garden every day for a bit of foraging and occasional frog eating (!).  Bingo has obviously decided that I don't let her out early enough as twice now she has managed to escape - who said chickens were stupid?? The fence around their run is quite high and deliberately unstable, but Bingo has discovered that if she jumps up onto the flap over the coop entrance, she is then able to fly out.  This morning I looked out of the window to find Mrs Weasley and Ginny looking quite anxious at the front of the run, wandering back and forth - something was obviously up..... I then saw cheeky Bingo wandering around the garden, picking up windfall apples!!
Job for weekend - Bingo proof the run!!
