Omlet Smart Autodoor - New in box

I have an almost 6 week old silkie that has been shaking her head for at least the last 3 weeks. I also have 2 others that do not. They are bigger than the shaky head one. She seems to be eating/drinking/pooping just fine. I thought that perhaps she was the one who got pecked in the head by one of my older chicks. Is this a possibility because of the peck on the head she has this shaky head problem or is it something else?

Could be parasites in the ear. I would get breeder or vet to check them for you.
