I have tried searching and found NOTHING. I have a 15 week old silkie and just two days ago I noticed her twitching her head. She looks like she is at a concert head banging. But it only happens for about 10 seconds and then shes fine. I see nothing physically wrong with her. I am almost thinking she may have some defects due to hatching very late. BUT I want to make sure this isn't something that is contagious. I have 10 other babies with her and I'd hate for them to contract something. I will separate them until I hear from someone. I feel like the others would have caught whatever this by now so I kind of need to know what to treat. I'm so worried! Please help!
