I would try it. There are some safe wormers to use, such as Valbazen or SafeGuard Liquid Goat Wormer. You do need to toss the eggs for 14 days after worming. I would look at how they are acting, to see if any are looking lethargic, ragedy, or are loosing weight. If you have a dog or cat vet, you can ask to see if they will do a worm test if you just happen to bring in some combined droppings. Mine has been willing to do that, even though he doesn’t see chickens. Amazon sells a worm test that you can mail in also, but I don’t have experience with it.
