Hi all, I have been thinking of using a de-wormer that a reliable user here on BYC recommended to me, called Ivermectin. I have found the stuff at a local feed store, but it only comes as a paste in a tube meant to be put down a horse's throat. I have no idea how to translate that into a dose to dab onto my chickens. Please help if you have experience with this. I'd be very grateful for any knowledge you have to share!
