I have three male geese and 5 hens. The males are: One Embden/Chinese, One pure Embden and one pure Chinese. The Embden/Chinese geese is too aggressive towards other males to a point that he doesn't let them eat even from a different dish. The Embden/Chinese geese just showed up to my pond. I have a feeling that he is a problem geese and the previous owner had to let him go so he dropped him by my pond. Today I caught him and tried to soften him by pushing him down to the ground as someone on this forum suggested but he is still hissing and chasing away the other two geese. By the way he hisses at me too. The bad part is that he actually beats up those other geese real badly when he catches them. I have 8.5 acres with a 3/4 acre pond so I don't see why 3 males should be able to live together. Any advise is appreciated or that big tough guy has to go.
