I was going with 2 weeks because that's what the bottle said for meat birds before process (and what I've read other people have done). I might play it by ear. I've thought about keeping the eggs and feeding them back to the chickens but that defeats the purpose...I might cook them and give them to the dogs after a week...I don't know. Of course if parasites are the hidden reason they've slowed down on laying and they start back again, it shouldn't take long to get caught back up.Usually the follow up treatments are around 2-3 week intervals. I understand about the throwing out the eggs. Thing is, there isn't a lot of information out there on how long any residue can be found in the eggs because most chicken medicine is based on commercial production information and they don't give stuff to chickens, they just kill them. It's really up to individual people as to how long they want to wait before eating eggs again. Most people I know that do routine deworming don't throw out their eggs if the eggs are for their own use and are not going to be sold or given away to other people.
