I have two bird dogs expected to protect birds against wildlife which they do pretty well. Dogs differ in age by about 18 months with younger proving problematic. Younger dog has proven more difficult to control and she miss-treats free-ranging juveniles when she thinks I am not looking. This has to be resolved with respect to the controll and harassment. What I have started is I brought inside a juvenile from same flock she harasses except the bird is a game while most are dominiques. Inside the bird has to walk on polished wood floor and dodge my 18-month old son that harasses chickens as well. Pup has lots of motivation to harass but I have increased controll over her. This shall be repeated daily to get pup to respond to my commands even when chicken is skating past her flapping just to changes directions or to avoid son carrying fork. She is already responding to verbal commmands which does not do well when outside. My son does not respond as well. Meal worms are used to keep most of interactions in same room with me. Pullet has started flying up on furniture and breifly faught her reflection in mirror but no damage yet. This will translate into better controll over pup outside as well.
