I have a question. In August I got a male and 2 females to start my flock. They got along perfectly then a few weeks ago we lost a female to a predator. We decided to add 2 more females to the group. The new females are under 3 months old. However, our existing female is really bullying them and not allowing them to eat. The male doesn't seem to care much for them and just ignores them. Our ducks are all free range so its hard to separate them. Will she reject the two new females forever or will she slowly adjust to them?
