Stuart, the general idea seems to be that a 7-14 day withholding period - both both eggs and meat is what has been suggested elsewhere. The reasons are a bit vague but may come down to that, as with many other medications, the required tests and results and expensive approval process have not been completed so product suppliers err on the side of caution to cover themselves in case of adverse human reactions to any residues. Some people are sensitive to sulpha.

I recalled this thread that if you haven't seen may be helpful but I feel that you'll still have to read between the lines and end up making up your own mind. :)

Question re Coccidiostat- reply from feed producer

The reason that they shouldn't be eaten is because there may still be residues or metabolites of that medication stored in the birds tissue and organs. It takes time for the body to break down, metabolise and excrete drugs out of their system. Some of the drugs have metabolites that take even longer than the drug itself to be removed from the body.
This is why we can catch sports drug cheats with urine samples often 200+ days after they have taken the cheat drug.

So back to chickens, most of these medications are anti-microbials. Eg antibiotics. The small amount that we may pick up from eating a chicken isn't enough to do us any harm ( unless we have a rare allergy, or the drug is chloramphenicol - but thats another story). But constant intake of small doses of anti-microbials are not enough to kill all the nasties these drugs are meant to kill. So over time these nasties ( parasites, bacteria etc) can develop superbugs that are resistant to the drugs. This is one of the main reasons for not eating animals fed on medicated feed, or that have been treated with medication until after the clearance time for the drug.

It can be a bit tricky to find, but you can get unmedicated chick starter if you want to use it. You do run the risk of coccidosis, but it seems chicks can still get it when fed the medicated stuff anyway. You just need to watch out for signs of coccidosis.

Red Hen make a non medicated chick starter, in a green bag and there is an organic one from Country Heritage stockfeeds.
