I have previously treated my peas with Safeguard and now it is the turn for ivermectin. I got some pour on ivermectin for cattle (5mg/ml) but have no idea how much to use on the birds (age 5-8 months). It says for cattle to use 1ml per 22ibs body weight. I am terrified of overdosing my babies. Does anyone know about tis formulation? Thanks so much!!!
