seizures

[larryjm21]

I have a 12 week old polish crested chick that seems to be having a seizure about once a week. Her head goes all the way back on her back and her tail feathers flair out. She doesn't seem to have any problem breathing and it goes away in about 15 to 30 minutes. Afterward she seems to have a hard time seeing, but that improves over the next few days.

I think she is eating something in the garden, but not sure what. Larry

There is a condition called wry neck that might explain your chicken's behavior. Sometimes it responds to B vitamins, as well as Vitamin E and selenium. Here is some info on wry neck: http://oureggbasket.blogspot.com/2013/04/wry-neck-or-crook-neck-understanding-it.html
Seizures can occur from lead poisoning, vitamin deficiency, head trauma, among other things. Here is another link to seizures in birds and their causes:http://www.avianweb.com/seizures.html
