I know this topic has been posted before, but I'm still a bit confused! I decided to give my girls pour on Ivermectin, since a lot of people seem to swear by this stuff. What I did was got an eye dropper, and put 4 drops each on the skin on the back of their neck... Was this enough or to much? How often do I need to do this? All answers are appreciated! I never did a proper intro! Just call me Classy! I'm 23 and live in southern Mississippi. I decided to raise chickens 3 years ago and have been enjoying every second of it~ I currently have 4 hens, 2 Red Pullets (though they are adults now) 1 Rhode Island Red, and 1 Black Star. I'm amazed on how my cats have no desire to try hunting them, in fact, they actually enjoy watching them with with me when I chicken sit!
