Errr. I'd error on the side of no.
I was worming the whole herd a few weeks ago. (Found some pinworms in a couple bunnies poop) And although I know one of the pregnant does has them, I'll wait until she's kindled and I've fostered the babies.
I even avoided the lactating ones. I don't want to risk it. I'll worm the mothers and babies once they're weaned.
