I've recently noticed the strangest behavior from several of my 5 week old silkie chicks. It almost looks like they're having a seizure. They hunker down, shake their head back-n-forth and it looks like their eyes glaze over. After a few seconds of doing that, they snap out of it and run around like all is well. I recently raised several bantie chicks in the same environment and they nver displayed this type of behavior. The only thing that I can think of is I recently used some cut-n-heal on my bantie hen where she was picking her wing. I noticed that tea tree oil is one of the ingredients and I read somewhere that some animals have a seizure like reactions to tea tree oil. I wash my hands but I can still smell a faint odor of it on my hands. What are ya'lls thoughts on this?
