Chicks acting off balance, help please! My bantam silkie and polish chicks are 12 days old, I incubated them myself (shipped eggs) and don't have any other birds nearby. About 3 days ago I found one in the middle of the night wheeling around in circles on its wing as his leg was paralyzed at the moment, toes on one leg curled in. Lasted about 3 minutes and back to normal. Found another doing the same thing a couple days ago for 5 min, back to normal. A third bird did this same thing today. I have not seen that first bird do that again, was only one time and only twice have I seen the second bird drag his wing around. They all are eating, playing, pooping, drinking and acting very normal. I can't figure out what's wrong and don't want to wake up to find them dead so I started treating for coccidiosis. 2 tsp (10ML) per gallon of water for 5-7 days. I'm still using the medicated chick feed unless I shouldn't? I've taken all other precautions with maintaining a clean brooder with a thermometer inside for the correct temp. What else could it be? Aren't they too young for Mareks? Also I tried oregano, apple cider vinegar and garlic which may or May not be helping (I removed the ACV when replying with corid today). PS they have not been vaccinated for anything. Please help!
