Henny pennies

My new chickens are settling in, and so I decided to give them a little more freedom and take the mesh cover away from their little run. All was well, they were pleased with the fresh grass and scratching areas.
Later on I looked and two had jumped their fence!
We managed to usher them back in, but I have reinstated Stalag Luft as I'm away for two days. Naughty things!
