Speaking from certain knowledge, ( I lost all 18 birds) the little rascal is indeed clever. Don't know if you read my post but shit came into the pen from about 7 ft up. How the hell did he work that one out. Just cost me an arm and a leg to get the new birds and sort out the 'secure' pen. Every morning I walk down there in leaded boots. Good news is they are all laying like mad so there is a silver lining. I've Cheshire Blues (pale blue eggs),black rock, white star, light Sussex and a lovely little banty running with an equally lovely little cockerel. Nice mix of colours agin with the eggs so
