I have two mallards that I bought at little babies, and they were so cute! They have always been very skittish. I have worked with them, held them, sat by them, stood by them, and they absoultely hate me! They will not come near me to even let me touch them. Is it because of the breed, or am i ding something wrong? I thought ducks were supposed to be cute and cuddly, like my hens.
