This Spring will be 2 years since our beloved duck Duke was dumped at our creek along with her sister (who was too sick to make it), and we took her in and fell in love. Shortly after Duke arrived in our home we brought in 2 ducklings who someone who lived in an apartment had bought and decided an apartment wasn't a good place for ducks (right?). They both turned out male, a Rouen and a Cayuga/Runner; Rhett and Link. Rhett and Link get along wonderfully, like seriously bonded wonderfully. They panic when out of each others' sight, are always following each other around, and really don't care if anyone else is in their presence. Rhett is obviously in charge though. The 3 of them, Duke (f), Rhett (m), and Link (m) have been together since Summer of 2015. The boys gave Duke a bit of a hard time last Spring, and I don't want to go through another Spring with her being the only female in the flock. For all the concern I had when the boys went through puberty they ended up not hating each other, and I would hate to now 2 years later cause fighting between them...we really want to get 2 females late Spring. I have no idea what kind of balance upset to be prepared for, and am still deciding if it is the right thing to do. Any help, thoughts, and advice are greatly appreciated. TYIA!
