I just noticed your location.No. I have never dewormed them. It wouldn't occur to me. What are signs that there may be worms to be concerned about? How do they acquire worms?
How would I go about deworming them? And would that be traumatic for them? ...I mean unless it were clear that there were worms that needed to be eliminated.
If I were to make a close examination of poo and saw some worm/s, how would I determine which hen needed deworming? Or would it be appropriate to deworm them all?
Hmmmm. Can I have their poo tested? I dunno. I will have to see what resources are available to me for that. But I live in a highly urban area so I'm guessing not a world of resources at my disposal.
You can mail some poop in to your state lab, if you really wanted to.
