I have raised may ducks and as babies, I once had 2 or 3 start acting really weird. theyd fall and barely walk, their head and neck swinging and falling back, and sometimes drool type substances coming out of the mouth. what is causing this? and what is it exactly? a couple survived but 1 has died eventually after this happening. help!
Welcome to BYC, it can be a niacin deficiency or a toxin of some kind, either one can cause symptoms your talking about. Sorry for your loss
