Please Help. My pekin duck stopped laying eggs last Sunday, she started laying again Thursday or Friday, but did not lay today. Since last Sunday regardless of weather she lays or not, she just sits around and her wings twitch and jerk a lot. She does get up to eat, and sometimes to swim a little, but mostly she just sits there twitching. I so far have not been able to find a poultry vet in my area (probably could not afford one if I did).
