When is it safe to eat the eggs?

[PNWChicky]

A couple of my chickens have started laying already and they have been on the medicated developer feed. I just switched them to a layer feed but i'm wondering when it will be safe to eat the eggs? How long does it take for the medicated feed to not be in their system anymore. I tried searching on the forum but i wasn't able to find anything maybe i didn't type in the right words or something.

Thanks so much.

I'd wait a week.
It's not poison but a thiamine blocker.

I'm pretty sure the anti cocci med in the feed has no withdrawal period. Should say on the feed bag.
