I know this has came up alot in recent threads but I have a question. So from my understanding you can't use ivermectin 1% injectable on the skin that's what I bought it for was for the use as drops on the skin but now with all the reading people are saying the pour on :/ will it still work as a drop? My fear is..is that if I add it to the water some birds may drink more than others and overdose. ..what are your thoughts?
