My three girls are running amok! A 20 wk old BR and 2 16 wk old sex links, they find at least one new way to cause trouble every day. So far they've discovered that they can jump up to sit on the fence, decided that inside my house is worth braving the German Shepherd Dog at the threshold and/or my my husband, they chase squirrels, robins, doves and blue jays and are determined to follow me everywhere. Today they learned to climb the maple tree, flapping madly as they clawed their way to a crook 6' off the ground (I think they're trying to chase the birds on the feeder). Do they outgrow behaviors like this? Do I need to pack them full of fatty foods so they're too danged fat to get off the ground?
