Yesterday I found a pile of poop with worms in it. Only two hens roost there, so it's gotta be one of them. Both hens look and act just fine.
Question for everyone to think about. What would you do if you found such a poo? There is no wrong answer, I'm just curious as to how you would deal with it.
Not sure since I've never had to face that. Speculation is easy but real life reaction can be quite different. If it were several worms I'd probably treat the flock since I'd expect that to mean a fairly high worm load. If I treat at all I treat the flock, that part I'm sure of.
If it were a single worm, I'd have a decision to make. Since I've never seen any which means they have not formerly been in this environment, do I immediately treat to try to keep them from getting a foothold here? Or do I accept that by the time I see a worm they are now established in this area so I can't eradicate them. In future I observe the flock and see if they area acting like worm load is high or not. Whether it was a roundworm or tapeworm would lead me to further study and might make a difference in how I react.
I seriously doubt that I'd start giving them ACV, DE, garlic, cucurbit seeds or anything like that as a preventative. Mine get cucumber and squash in season but that's not a treatment, it's just garden excess. I haven't seen anything to make me believe any of them are all that effective. The only study I've found that I trust was on goats, not chickens. The results were between no don't help to inconclusive at best. The one that was deemed worth further study was cucurbit seeds, but some of their initial tests showed sometimes the results were better but sometimes the results were worse. That probably means there was an untested variable in those studies, maybe not the cucurbit seeds. The goal of that study was not to totally eradicate the worms but to find an effective organic solution to improving performance, that is minimizing the effect of a worm infestation.
