I bought ivermectin ‘pour on ‘ —works in a day. I have never tried the oral and my thoughts are it should work any time soon...? As it gets through their system. Idk ...
If you do get the pour on it’s 5 drops dispersed through wings vent back for standard birds. 2 drops ( back and vent area) for bantam.
