I want to worm/de-mite my flock with pour on ivermectin. I did it once before and I think the dosage was .5cc for a standard and half that for a bantam. But what if you have a really big standard or a really small bantam? I know if you put on to much it can kill them, and if you don't put enough on, the mites and get immune to it. I've also heard that you put like 5-6 drops on a standard and 3 for a bantam I also have a Turkey how much do I put on him? I'm confused!
