Mine are both intent on getting down the side of the lean-to between it and next doors fence when they're freeranging. Its really hard to block off properly because the back door hinges open next to the gap. It is 4 inches wide. I think they just like to do things they aren't meant to. Mac has got down there twice, despite knowing from the first time that a) there's nothing interesting down there and b) its too narrow to turn round so there's 7-8feet of backing out to be done :roll: The last time they both got down there - Mac, who had gone in first decided he wanted to come out first too - some amazing backing out/walking backwards over Albie... :lol:
