Yesterday, I separated the brown runner ducks from the blue runner ducks. This evening, I found a nest in the blue runner duck pen, that initially appeared to only have one egg. I was surprised to find about 2 dozen duck eggs in the nest. Since some have been there awhile (there was a silkie egg in the nest and the silkies came out the day of the first big rain, I am going to boil them and feed them back to the chickens. It is amazing how they can hide a nest in plain sight when there is 6 inches of straw in their area. Now, I need to find some information about how long the blue runners could still be fertilized by the brown drake, then start hatching ducklings once the "all clear" time is over.
They seem to know how to do that well. I've had that happen, too.
