I need to deworm my chickens. I have one I'm pretty sure is not going to make it if I don't hurry. But I can't find anywhere that has any. The feed store doesn't have anything and the vet says he doesn't have anything for poultry. I'm wondering....I'm in farm country. There are a gazillion animals I'm sure are dewormed regularly and our vet has a refrigerator full of meds that farmers come and select from and pay for at the front. Surely there has to be something in there that, at the right dosage, would deworm my flock without de-chickening them as well?
