I got the polyvisol and aspirin today and gave them to her as soon as I got home. My vet is not a chicken vet. Although they go on farm calls i'm sure it's not for chickens. There are several vets in the clinic and I seem to have better luck with just one of them. He is the one that gave me the vitamins. I didn't look at the ingredients now wishing I had. I've tossed the other bottle of vitamins so I don't use it again. I just got online so I'll go and check that link you posted. I have that web site in my favorites already. It's a very handy one to keep.That's way too much iron, are they poultry vitamins ? If you feel that this is a cerebral hemorrhage a short course of prednisone may help with the swelling, however if it is wry neck or star gazing thiamine and a little vitamin E would be more effective.
