My duck is a two week old girl Cayouga. Today I had cleaned out my ducks brooder and was placing my Cayuga back in. She took two steps then fell over and went ridged. Her eyes rolled back in her head and she started convulsing slightly. After about a min she came two. She was notably tired. Then after about another min she started ti get her spunk back. I put her back in the brooder and she ran around like usual. I have no doubt this was a seazur. She is eating and drinking well. I am feeding her and my other five ducklings pureanas flock raiser. I am giving them grit and nutritional yeast on there food. (Nutritional yeast has more nican in it then brewers yeast ) I just add a pinch or two to there 1 1/2 cups food that I wet down a bit with water. They have been at 80-85°. My other ducks are happy healthy and growing great. I understand that this may be something she was born with and that's ok. What I need help with is, is there anything I can do to help her ? What do you think?
