I would like to dose my serama flock for parasites and worms I have bought some Ivermectin but am unsure if it is the right stuff The box reads Ivomec super (Ivermectin & clorsulon) Injection for cattle and sheep.Can this be given oraly or dropped on the skin and how much should I give to each bird.I only have insulin syringes for measuring am I right to assume 1ml is the same as 1cc,Thanks in advance
