A week ago my rooster disappeared . Gone for 24,hrs . ( heard a squabble , didn't think much about it ) went to give a snack to the group , no rooster. Looked everywhere . He showed back up& was a bit frazzled & upset & not to active with his girls . A week later found a hen dead in yard ( we have a 5 ft fence ) now yesterday , I heard a squabble & went outside & rooster looked upset( I failed to count my chickens ) one hen just vanished !! No evidence no nothing . My dog in the house . He has shown no aggression towards them ever . I'm watching him closely at all times !
