How to stop uncontrolled head twitching?

[Parkbenchchickens]

We have some chickens that have a uncontrolled head twitching. I know that it means that they have parasites but I don’t know what to do to help them. Anyone have any ideas?

Same chicken(s) as in your other threads?
Can you please post some photos or a video of their actions?

You mention that you know it means that they have parasites?
Have you checked them over really well for lice and mites?
Looked in the ears for infection?

Giving more information would be helpful.
How old are they?
What do you feed?

In one of your threads, you posted a video which is non existent now - it was suggested that the hen was adjusting her crop. Give us a link to that video too.
