I keep hearing about how friendly Pekins are. Hmmm. Ive added a Pekin (now 1 week old) to my 3 mallard babes. He loves them and they he. But...... he is a bit aggressive when we handle him. He calls for the others, tries to get away and when that doesnt work he latches on to a piece of skin and attempts to shake it like a pitbull. Amusing now, but wont be when hes full grown ! I try to handle them all as much as possible and all are agreeable except for this guy. Any comments or suggestions ?
