What type of (liquid?) Corid is safe for chicks? Med. feed too, or no?

You don't have to wait. Corid is not an antibiotic, it's concentrated amprolium like in medicated feed.

Yes but the medicated feed is not to be fed to layers either. The withholding period for eggs for human consumption is 10 - 14 days after stopping either the treatment type of amprolium or the medicated feed containing it.

EDIT: A withholding time for Amprolium is stated for laying chickens in many countries. For example, in Australia Amprolium products (e.g. Keystat) come with the statement "Do not use in birds which are producing or may in future produce eggs or egg products for human consumption". And medicated feed containing it has a withholding period for eggs of 10 days after stopping the feed.

Why the same warnings are not given in the US is a mystery. I'd be erring on the side of caution.

You can do that if you want, of course, but amprolium is only a thiamine analog, not a sulfa drug or an antibiotic. It should cause no harm whatsoever if you eat an egg from a hen who has been eating medicated chick starter with amprolium. Some starters have more than just amprolium, but even then, the amounts are so small, shouldn't be much issue with them, either.

Most folks raising chicks who then start laying while on the starter do not have to throw out any eggs. At that point, they usually switch the pullets to layer feed anyway.


And this statement makes NO sense at all:

That would mean NO one would EVER feed medicated feed to pullets. Sorry, but honestly, that is just silly. Of course, most chickens ARE being raised to provide eggs and most are on amprolium feed. That would mean you could only feed medicated starter to male chicks. No way that is going to happen and it's patently ridiculous, IMO.

Don't tell me that in Australia, they feed medicated feed exclusively to rooster chicks, never to pullets. Are you telling me that no one feeds medicated feed to their pullet chicks in Australia, in light of that instruction quoted above??

And what is the point of a withdrawal at all if they aren't to have it in the first place? That is very contradictory.

Here is the statement above in the Keystat product data sheet. Residues are mentioned as an issue in some countries. http://www.iahp.com.au/datasheets/Keystat Powder.pdf

The other statement about withholding periods applies to Amprolium used in chicken starter crumbles and other products containing Amprolium. I don't have time to find them again but you could googlesearch it.

Speckledhen is correct, there is no withdrawal period using amprolium in this country, maybe yours...but not ours. I've used it and I'm still here typing.

Thanks for those links dawg53. I must say I'm unimpressed with your FDA's safety regulations, but there you go. No withholding period in the U.S. when most other countries are firm about it...wow. I guess if someone developed a lifethreatening thiamine deficiency from it, as horses are prone to do, no-one would make any connection because there are no warnings. It's up to each of us to be informed and aware I guess. Thanks again for those links.
