This is a question mostly for my mom, but I am also curious for my chickens eventually, because Id like to have healthy anti-parasite routines. My mom has the 1% injectable ivermectin thar she got for her chickens, to be applied topically. Can she use this or only the pour on ivermectin in that way? I found the dosage for the 5% pour on in several threads,but is it the same number of drops if you use the injectable kind topically (since they have different ivernection %s)? Also will it only kill mites ans lice applied topically, or also internal worms? I suspect she has both, so I think she needs to use some Wazine first anyway? Or is just Wazine plus using Sevin a better option? Thanks!
