These are the first ducks I've ever had. I built a caravan house for them with a pen, for their safety. But they prefer to free range. Over a month ago I found "Esmerelda" had made a nest under one of my palm trees (I live in South Florida). There were 3 eggs. I checked the next day and another was added.then the following day, there was only 1 egg. There are couple of stray cats that wander into the yard. Anyway, I took the egg and put it into the caravan and started locking them up during the night. She continued to lay eggs and then after a few days I gave them their freedom. She returns every night to lay an egg. I have removed some eggs for our own consumption, but have always left at least 6 for her. Since she continues to lay eggs, I decided to stop taking any for myself to see if she would sit on them. She has 17 eggs in the nest, but shows no inclination to sit on them. To date she has laid a total of 32 eggs. I thought 12 was an average for a clutch. It seems a shame to waste all those eggs, if she's not going to sit on them. But every morning I go out and she and Quasimodo are enjoying a swim in the pond.
