It was in the spring or summer of 2010. I don't remember exactly. I was surprised, because yeah, if someone only orders 2 it's generally because they really only want 2. I think it was just a mistake on their part. Still, if I order there again (and I wouldn't hesitate to order there again), I'll make sure to specify to please only send exactly what I ordered.
When was this?
I ordered 3 females in Aug 2010 and received just 3 ducks. They are one of the few hatcheries that let you do an order between 2-9 because they know you don't want a bunch of extras arriving to your doorstep.
