I've just entered the world of duck keeping and have welcomed this pair from a small suburban courtyard to our farm. The people had them as pets and sold them as '2 purebred Buff Orpington ducks.' I was planning to get a buff orpington drake to add to the family but, after letting them loose on them farm, I'm fairly certain I have a drake and a duck, not 2 ducks. I haven't seen him do any male types of behaviour with the female yet though. Can anyone help? If this is a drake, he doesn't seem to have the striking Buff Orpington features, like a clear neck line and yellow bill but there is a curled tail further which tipped me off. Thoughts? Do I have a boy and a girl?
