I've dewormed my hens Saturday morning with a product containing Fenbendazole. I've been reading about it on the forum and it's been suggested that humans don't eat the eggs for a while. So we decided not to eat them. A friend of mine wants the eggs to hatch and I now have a broody sitting on eggs that was laid Sunday morning. Will there be residue in the eggs and will it have any effect on the embryos?
