I live in the Pacific Northwest, I have a two Chinese Weeder geese. A girlfriend bought them from a local farm store, turns out they were both females. They are almost a year old. We are actually thinking of butchering them, is that too old for eating? The reason we are considering this is I have a Rouen (female) who is broody, an three young Anconas (2 mos old). My weeders chase the Rouen away, they seem to think the ducklings are theirs. The ducklings seem to be very nervous around everyone, and run from the geese. What can I do to bring harmony back to our farm?
