So i bought "mallard" eggs online and only one hatched but it turned out to not be a mallard, it was a pekin. So my mom and i read that they can't be alone or they'll be depressed, we didn't want Boo to be depressed, so we went to a nearby farm and picked up a one week old Blue Swedish duckling named Daffy, this baby is a female they told us and we didn't know about Boo. But now we found out that Boo is a boy. we don't want anymore ducks, so is there a way to stop them from mating? Or will we have to get rid of Daffy? we don't want Boo to become depressed and Daffy has already seemed to imprint on me and Boo. What do we do?
