I have a little araucana that went broody in a hutch in the duck pen. She had been laying in there for a long time, along with the Rouens and Mallards, but I would clean out the eggs every few days. One day I started seeing duck eggs all over the yard and went to check the hutch to see why. There she was just sitting there having gone broody. I knew I had just cleaned out the eggs a couple of days before so if any were there when she started sitting they were probably duck eggs - so I slipped her a few freshly laid hen eggs and she has been sitting for almost a month. This morning I peeked in and saw this: It's a little duckling. I also think I saw a baby chick head but mama broody wouldn't have any part of letting me look under her. It's going to be so cute watching her raise her clutch of ducklings and chicks. That baby Rouen will be bigger than it's mama in less than two weeks.
