the dragon being the neighbor's dog, a 150 lb. cur named duke. while duke is a chicken eater, this is not the problem. he is well restrained (invisible fence) and i rarely lose any chickens to him from getting free. (his owner pays for the rare one lost.) However...... my knights errant (roosters) want to slay the dragon. duke sees them coming into his run as kfc delivery. can't blame the dog or the owner since it's the chicken entering his area. how do i stop them from doing this short of keeping them in a pen. doesn't happen very often, the hens stay away from the dog.
