I have a mallard drake that has been aggressive his entire life. He loves his mate and she actually pushes him around, but he HATES me and my family. Whenever we come into the cage to clean the pool, give food or change the water he chases us around and bites at our feet. He use to only chase us when we had our backs to him but now he'll attack whenever we come near him. He bit me so hard today that he actually drew blood. I'm scared to even go and see my girl now. I have Call ducks hatching and I wanted to put them in the same cage when they were old enough, but now I don't want to with the aggressive drake. Is there anything I can do to calm him down or is it time to say good-bye?
