We are fairly new at raising ducks. This is our second year. We have 12 Cayuga ducks, about 1.5 months old. We're planning to breed them. Early last week, one of them had a seizure right in front of us, very suddenly. It went from playing with its fellow duckies to rolling around on the ground. The head goes straight back and the muscles all become very stiff, like in rigor mortise. We have her a syringe full of honey and electrolytes and she improved rapidly. Today, it happened again. I think she was down for longer because I didn't notice until the others came over. I'm giving the electrolytes and honey and it isn't working as well. She's not importing quickly. What is happening? It seems to be clearly a nutrient deficiency, I'm using a different brand of electrolytes. None of the other ducks have ever had anything remotely like this. Need help! She's on my lap right now looking very droopy.
