I have a 4.5 week old Buff duckling who has been acting peculiar the last couple days. She swings her head around, runs crazy, and ends up stuck on her back. The only thing I can describe it as is drunk. Not sure what to do. She isn't eating or drinking as much as I would like, but if I hand feed her and water her, she will eat and drink. She has plenty of energy to run off scared whenever I get near (which isn't normal for her). She falls over when trying to preen as well. When I checked on her this morning she was laying on her back. It looks like she fell over and got stuck there last night. Poor thing. The only thing I can think of is Botulism. It has been very hot and wet here in Georgia lately. She does get brewers yeast in her water for niacin. Perhaps that could have been it? I have since stopped giving her niacin. I have given her water with Epsom salt for the last 24 hours with no improvement. She is on unmedicated flock raiser crumbles for food.
