My pekin duck was flopping on her back

[Bjwkarma]

She couldnt stand right, she would lay on her back and like keep moving her legs like shes walking, then she was acting like she was eating... i dont know i honestly think her mind was not right that she was poisoned... there are mushrooms around here... is that possible? She seems better but her equilibrium isnt totally right yet. Anyone have this happen?

Never actually had this happen personally, but whenever I started raising ducks, chickens, quail, and turkeys I googled herbs/plants toxic to poultry. What kind of mushrooms? Can you add video of your duck to this thread? And picture of mushroom? Is anyone else in your flock acting this way?
