I have a 6 month old mallard female. Three times now, all of a sudden, my duck can't walkl or fly. It's almost like an inner ear infection, or as if she has no equal Librium. In the past I've just given her water and an egg yolk and put her in a dog crate to rest. The next day she's always fine. Today she flew into the island in my kitchen ( I think) and now can walk, she shakes, is lethargic, won't eat, barely drinks and is quiet. She laid an egg this am which she does from time to time about 6 eggs altogether. The only thing I see that remotely seems like her symptoms is botchilism but I can't see her having that. I take very good care of her. She's an only duck that the others wouldn't accept her so I've been mamma. I'm scared, any suggestions????
