I use Ivermectin pour on "off label" several times/year to treat my chicken flock for mites. Since, it's off label, they don't have a listed "egg or meat" withdrawal time. But, since it's being used with good success to treat covid in other, more progressive countries, I have no qualms about eating the eggs that are laid "the morning after" or in the following days. I figure, I just might loose a few parasites along the way, and will have my immunity boosted to ward off any covid. Perhaps, based on the latter, I'll also be protected from covid death caused by motor vehicle accidents, being trampled by elephants, or good old influenza.
