My Auracana chicken INCESSANTLY shakes her head. After spending hours on this forum and the internet, it was generally a sign of mites/lice. I did not see any, but went out & got the Ivomec Pour-On. I dropped the 5 drops on her skin. This was last week. Nothing, no change. It appears to be worse. This has been going on for weeks. I'm totally stressing over this because I cant find anything concrete that points to a specific problem, but I feel something is wrong. The other hens are normal. Poop- mostly formed with a yellow tinge to the uric acid component. No blood. Feed- Organic layer pellets, treats like BOSS, scratch grains and veggies. I see her eating. Age- 7 months, not laying yet Condition- VERY thin. I can feel her breastbone. She is very light. Crop not full. It almost feels hard, but not sure. That was just today, I'd have to make more note of it. Water- ACV added to water Bedding- Pine shavings in coop, deep litter. Poop boards cleaned daily NO signs of Upper Respiratory problems, sneezing, wheezing or open mouth breathing. I even turned on a heat lamp in the coop for her thinking maybe she is cold, but nooooo, she could care less and hangs outside in the run, and mills around in the snow. She has never been wormed before the Ivomec pour-on last week. Should I try some Eprinex pour on? I'm stumped. At a total loss Does one of you experienced folks have any idea what on earth is going on?? Have you seen this before? She is an odd chicken, behavior-wise, and I'm almost wondering if this is a tic she's developed? She is not picked on or bullied. Shes a loner. Stands around by herself alot. Sometimes got a droopy wing look about her. First one out of the coop in the am like shes ready to start the day, but........ I have to do what I can if its a medical condition.
