I have a bottle of Ivermetcin INJECTIBLE for cattle. I have read that some put ivermectin pour on, on the backs of chickens. I'm wondering if I can do that with the injectible? I know to use just a couple of drops on bantams, and a tiny bit more on larger chickens, of the pour on. And if It is OK to do this, do I need to hold off eating the eggs, and if so, for how long? I have been reading several hours today, and can't seem to find the exact answers I need. I have seen mites on two chickens..have looked at 4 others and don't see them. Makes no sense to me. I'll treat them all (32 chickens). I have guineas and ducks that will be impossible to catch, I fear. They all interact nicely, so I hope they are not carrying any mites. I have treated the two that I saw the mites on, with DE. Thanks!
