I need help. I have a pair of mallards that I have raised since they were a few days old. Our female is sweet and a little shy, but our male has become more aggressive over the past few months. He constantly chases and bites my feet and legs every time I go into the yard. For some reason he does not do this to strangers usually just me and sometimes my husband. Have I done something to make him dislike me? What can I do to correct the problem, cause I gotta say it really hurts when he bites!!
