My gander is still not being cooperative. Now he hisses at me and still bites and flogs me. I can not be alone with him. Somebody has to control him with me. I sat on him once to control him, and that works a little. I do not know what to do.
Like jchny2000 said you have to keep it up. Take the broom with you when your out with the geese and when he flogs [or tries] don't even let him touch you, pop him good with the broom, Not to injure him but just to let him know he cannot touch you in the manner he wants too.
This is very typical behavior not anything out of norm honest. They are just acting like protective ganders during breeding season. But you need to reinforce his training everyday, and not let him get the advantage. I am dealing with 2 gander this season and let me tell you so far neither have learned so it's everyday here go out side to give extra food or just walk in their area they think they have to chase me away, but I do not let them get away with it. . It will all be over by end of May so just try to keep on with training.
