My earlier post seems to have been lost along the way. If you are feeding medicated chick starter you should cease when you suspect wry neck. Thiamine ( vitamin B ) deficiency is one of the main contributors to star gazing / wry neck. Amprolium used to control coccidiosis is a thiamine blocker.
It works on starving the coccidia and at the same time can cause a deficiency in some birds.
There is no way of knowing which vitamin your bird is lacking in, so it is a process of elimination.
If it is thiamine then stopping medicated feed and administering polyvisol may bring results.
You beat me to the punch with this info. Thanks for chiming in, you lifesaver!
My friend had a free day-old incubator chick given to her to nurse about 3 years ago however we didn't know what to do for it. It was a LF chick (don't remember what breed) and we spent days trying to keep it standing and holding its neck but as soon as we let go when we thought it was standing, it threw its head and fell backwards but on its back still tried to peck at the feed. It still had an appetite but couldn't eat standing up. Little did we know THEN about giving it the vitamin treatment as wry neck seems to greatly improve with the vitamin B. Sadly it was culled by the original breeder who didn't have time to spend with it.
What dummies we were and didn't know about BYC then! Again Fancychooklady to the rescue! Next to my vet she's a wealth of help!
