Thought I would take a photo of the broody duck, I put 12 eggs under her and she has been sitting on them for about 9 days now. Incubation period of 26-29 days so it will be a little while yet until we see any ducklings.
UPDATE 20 June 2016: The eggs hatched today, added photo of the ducklings and photo of eggs in nest from last week. I think I counted 8 ducklings but until she comes off the nest I wont know for sure.
UPDATE 22 June: added pic of the ducklings first day out!
