my first time here,I lost 5 beutiful astralorp hens to some type of critter,woke up one mornng and all five were outside the pen dead,sometime during the night something found a weak place in the wire and got in,one was partly eaten and the rest were just killed,I suspect a dog,I have put 1 inch welded wire around the poultry wire,4 feet up,added electric fence around the bottom and top of the wire,installed 4 nite guards that I ordered,six strands of barbed wire on the coop door,shotgun standing at the back door,anyone got any ideas??,they were chickens but they were my pets,
