The time from ripening yolk to laid egg is about 2 weeks. So most folks wait that long before eating the eggs. That said, that drug as well as most drugs we use are officially off label in laying hens. The bottle says not to use it in laying hens. What that legally means is that the withdrawal time is for life. I would pay attention to this if you sell eggs, or give them away to people- as many people really really hate the idea of drug residues in their food. There is no legal leg to stand on if you sell eggs and use off label drugs with no published withdrawal times, and someone chooses to get uspet. If you and your family are the only ones eating the eggs, then you can do what most people do and wait 14 days.
