Here in the US, medicated feed typically has thiamine-based Amprolium in it, a coccistat. Sulfaquinoxaline and amprolium are both coccistats, however. It's usually fed to youngsters in starter feeds, as they have less resistance to things like Coccidiosis, an illness caused by a protozoa. It may easily differ where you are, but among the items you listed I don't recognize any 'medicine', just supplements.

Whether it is safe for your ducks, I don't know. Ducks can require quite different feeds from chickens for optimum health. Hopefully someone with more duck experience can chime in, such as motherduck.

The feed I bought from the other mill did say "medicated" on the label and also said "With Clopidol (COYDEN) at 0.0125%". What confuses me is that when I asked for "non-medicated" feed nobody knew the answer - as if they though vitamins are medicine.

Very few feed store employees know anything about the specifics of the feed they sell--mine don't, either. And they'd never admit it. When I asked for medicated chick starter they stared at me like I was speaking gibberish. :(

Clopidol is another coccistat, it's a medicine.

My feed store also does not know how to distinguish a roo from a hen in any breeds except the most common--I bought two buff laced Polish hens from them that they swore were roos (I told them up front they were not, and told them how to tell the difference).

I also bought a WCB Polish hen, who was not only sold to me as a roo, but 'mean' as well--because this poor little hen would calmly walk up to people, stand politely at their feet for a moment, then gently tug on their pant leg ("It's attacking me!"). When we heard this we just laughed, and told them that was Pet Chicken for 'pick me up'. We were right, she's a lap chicken and a spoiled baby. :)

So don't go by what feed stores say, read the label. You probably know more than they do. :)

Waldmann, are you raising cornish x type meat chickens? If so be sure the chick start has enough protein for their rapid growth. I think most people look for a protein level from 18-21% Tom

Well, the place where I buy feed is not just a feed store (I avoid these as the feed tends to get infested with bugs sitting in storage) - it's a mill where they do more than just selling what comes to them in bags. I'd figure they should be more knowledgeable about feeds. Two things though - the Mennonites who run the mill are from Canada and English is not their mother tongue but low German so there might be some miscommunication and misunderstanding when it comes to specific terminology, which varies from one place to another, I suppose.

The hatchery here only sells two breeds - Cornish x, and Hi-line brown, both bread for very specific and narrow purpose and highly efficient at that. I can get starter and grower feeds for both broilers and layers and also finisher for broilers and layer mash. None of them contains anything which I could trace as "medicine".

My first batch of broilers was brooded in a traditional way which proven too effective and a few of them dropped dead because we weren't slaughtering them as soon as it was necessary. It was a learning experience. The next batch we're raising with some Hi-line brown roosters, who go around, scratch and forage and Cornishes seem to follow the good example. With Chinese geese guarding them they're out free ranging all day and seem to be much fitter and lively than the first batch. They're really tasty too :)
