So the barn I got my chicks from has a way of preventing coccidiosis besides medicated feed, they have you give half a dose of amprolium in the water once a week(along with feeding their blend of chick starter feed).. I read somewhere that antibiotics can cause vitamin deficiency and one of my chicks currently seems to be having problems similar to vitamin B2 deficiency. Their water has probiotic/vitamins in it right now, I've been giving a little extra to the problem chick with only mild improvement. They want you to do the treatment on Monday and I'm debating on if this is a good thing for her right now? I don't want to make her worse ;(
