Thanks for the replies! My chicks have been headshaking and doing the "gape" movement for MONTHS now--October it started when I brought home 3 headshaking silkies. It seemed to spread to the baby Orpingtons and now they all do it...they do it more when they are relaxed in their hutch.
After my last post, I went ahead and gave them ivermectin 1% in their water (1 ml per quart) for two days. I did not notice any difference in their behavior and besides some lose stools for a couple days, I didn't notice anything out of the ordinary for the worming-no expelled worms, etc.
They still seem the same and it's now 4 months later.
No one seems sick...just head shakes. They don't seem to shake their head when they are running around outside...Stress??
No coughing sounds/sneezing...they had been sneezing at one point, but I don't hear it anymore.
I'm sorry to hear about your baby...I am glad you caught it and saved the rest of your chickens.
Did you look at my video? Did yours headshake like mine? Oh..that wasn't the post with the video. Check out
