That's the reason I stopped using medicated feed years ago and went for organic feeds. The last bag I remember buying smelled odd, and there was no way I was going to feed it to my chicks. I can control the Amprolium dosage myself by using it in water. Never had a problem doing it that way.If you are feeding medicated chick starter, it might have too much amprolium in it. Amprolium in larger quantities can cause a thiamine deficiency leading to wry neck. I spoke with the vet at UCDavis School of Veterinary Medicine and she told me about some feed having too much Amprolium in it. I had a cheap brand of feed and out of seven chicks, four had wry neck within a few days. I tossed the cheap feed, bought unmedicated feed to use to use until they were well again, then restarted them on Purina Medicated.
