So, is medicated feed safe or not?

[Smartie_Pants]

I always heard that it was toxic, and now I've read that its only toxic if it contains a certian medicine, and most medicated feeds don't have it anymore. What is the "bad" medicine and is medicated food safe as long as it doesn't contain that medicine?

Here's a thread that talks about this:

I know nothing about ducks. Found this by searching for medicated feed on the ducks forum.
