Hey guys. I have another problem that hopefully you can help me out with... About two weeks ago my girlfriend and i bought twp Swedish Blue ducklings, and then maybe three or four days later, we picked up two more Mallards. The four of them got together great, and have been super pleasant and totally cute. Today though, we picked up another two Khaki Campbell ducklings (probably 2 or 3 days old), and tried to add them to the mallards/blues. The four older ducklings instantly started swooping in on them, pecking at the khaki's eyes, grabbing their wings/necks, holding them down, etc... They will literally not leave them alone. quite honestly with how rough they are being to these newborns, I'm afraid that they wont last that long. Is this normal? Can i get them to stop? Is it a matter of just watching the six of them closely enough until they start to get to know each other? Or are the khakis just too young to keep with the others? I honestly had no idea that just two weeks would make this massive of a difference. My ducks are killers! help!
