Haha! the same thing happened to me when I first started chicken keeping! I heard deworm and I was like whaaaaaat? Deworming is one of those issues where you will find people for and against it. Kind of like the supposed vast benefits vs true dangers in feeding Apple cider vinegar (cue the yelling here from peopleWait....sorry to hijack....i was suppose to deworm my chickens?

Definitely if you see worms or a bird seems like it may have worms then you deworm. You do not ever HAVE to deworm without an issue present. Not like puppies.
