Quote: Sidhe13 While you can ferment the medicated chick starter, the issue you are going to run into is that the chicks most likely will not eat the fermented starter in a timely fashion. How many chicks, how old are they, and how much feed got wet?
Medicated feed can be fermented and it will not cause the issue that Evan is suggesting. If any thing at all happens to the Amprolium in the fermented feed, it will most likely loose some of it's potency. I'm not a pharmacist, and I doubt that Evan is, though I could be wrong. So... I'm making a wild guess that fermenting medicated feed should be just fine for you. But, you are not likely to use it before it is too old to benefit them nutritionally. Nor would it be wise to just continue feeding it after it has gotten wet. Mold can be very toxic to chickens.
ETA- This is an old post by Sidhe13. But a recent response by EvanW. So, I'm responding to clear up any misconception re: fermenting medicated feed. I personally don't use medicated feed, have been fermenting for 4 years, but it is perfectly acceptable to ferment medicated feed.
