I have 2 pekin and 4 mallard ducks the mallards are 3 weeka younger and pekins are much bigger. I want to put them all together but im worried about them hurting the mallards. I took one in to see how the pekins would behave and one ran up and chested the little one. Should i wait a few more weeks how long till mallards reach full size? Any advice or am i just to worried and they would figure it out?
