Feed with Bacitracin Safe for Chickens??

[chickenlady]

Is anyone familiar with this? It is the medication in the feed I have. It is a sportbird flight developer. Will this be safe for my chickens?

Sometimes it is added to help fight cocci and necrotic enteritis. At the levels they add it, I am told it is safe, but I really would rather only have Amprolium in mine.
