I have seen in past posts that some of you folk use Ivermectin (Ivomec) as a wormer on your birds. I really have not had a problem with worms, but have decided to start a worming program for the sake of other birds that we now raise. We use Ivermectin as a drench on our goats and my wife uses an injection on her rabbits, but I have not seen how it is administer to chickens. I assume that it is broad spectrum because that is why we have used it in the past. I looked at First State's website but they do not list how it is to be used on poultry. Can anyone help?
