Frankly I doubt that 'giting more girls' is going to help your problem but that is just an opinion. My opinion is that you have a 'pecking order problem'. pecking order is what allows flocks to exist, every bird has to learn who he/she can dominate and who can dominate her. These two drakes have learned that they can dominate you by making you back down and even chasing you. Every time you come back they think you are challanging them again so they try to put you in your place. You MUST stand firm and back them down. Since they won their early matches with you, they will take some convincing that you are trully the boss and they quit. nudge them back with you foot, carry a stick if needed and push them back with that. You have to convince them that you are boss when you are there even though they may be the boss when you aren't. sooner or later they will learn and quit trying. ~gd
