I have a seven week old duckling that I noticed having a seizure on Sunday then again on Monday. I’m not out there with them all the time but I suspwanna car she’s had more than these two. Afterwards she is wobbly and has trouble walking for a while. She seems lethargic and isn’t eating or quacking as much as she normally does. And now I noticed her eyes have been crusty and the left one she intermittently keeps closed. I have one other duck that’s the same age that appears healthy. They are in the same pen as 9 chickens. I think she is a buff Orpington but I’m not sure. She does have a little tuft of feathers that comes off one side of her head so maybe she’s some kind of crested duck? I’m not sure if that could have anything to do with her seizures or not. I feed them game bird crumbles and chicken feed as well as meal worms and some table scraps. They have hay for bedding inside the coop where all the birds sleep at night and a shallow swimming pool that they play in. I’m baffled and really worried. She’s so sweet and I don’t know what to do. Any advice would be so appreciated.
