I have never had this problem with my ducks before. I got four ducklings a couple weeks ago and a few days ago one of them started being unable to stand and hobbles around on the backs of its knees with its wings held out for balance. It cant stand at all. I've given it electrolytes, vitamins mixed in its water, and nutritional yeast. Not all at once, but in general and continue to put the nutritional yeast on it's food. It's half the size of the other ducklings and none of the others are having problems. I'm kind of freaking out and would appreciate any help. TIA
