I picked up a couple of small bags of chick feed for new babies I'm getting this weekend, but accidentally grabbed one medicated. I don't care about the money enough to drive all the way back to return it, but wondered if I could just use it and not buy another. The question is more, HOW should I use it? Should I feed it at the beginning and then switch to non-medicated, or save it for if/when someone gets coccidiosis? Mix it 50/50? Or just give the whole bag to someone who uses medicated feed? Does this even matter????
