I have got some egg questions. I have 9 ducks (2 drakes, 7 hens), White Layers and Golden 300's who are prolific layers. They turned 1 last August (2017). They started laying in January 2017, (back when we had 8 hens) and once they all started laying, I was consistently getting 8 eggs a day until the days got significantly shorter (October - Novemberish). We lost a duck in September. Throughout winter they have been laying 4 to 5 eggs. Mid-February they started laying 6 eggs most days and continued doing so until about a week or so ago. It has been very inconsistent - 6 eggs one week, then 3 eggs, 2 eggs (lowest we've ever gotten), 6 eggs, 5 eggs, 4 eggs, etc. Also, we got quite a lot of soft shells. We gave them crushed up egg shell (had to mix it in their feed because the wouldn't eat it otherwise) but I stopped once I saw bits of egg shell in their poop. Is it more likely that one is consistently not laying (getting 6 instead of 7 eggs) or that all the ducks are taking turns not laying? What could be the cause of all the soft shells? How can I know who is laying and who is not? One duck has suddenly become almost completely immobile due to swelling in her foot, which has happened to her almost twice before, she is being treated so I wouldn't be surprised if she wasn't laying, but it only showed up a few days ago. Everyone else is acting perfectly normal, they have been getting same diet, and there aren't any obvious reasons for stress - it's Spring and our drakes (one especially) have been chasing them around, but nothing new. (Although one is repeatedly targeted). Sorry for the long post.
