I am not sure the exact withdrawal. I wait 6 weeks before eating the eggs though. Figured it was the same as safeguard.
My husband has been grumping about not having any eating eggs for two months (I did a second dose two weeks after the first) I am thinking of buying brown eggs and telling them they came from our birds
Well, I bought mine from tractor supply. I also use the Pour On, and used a syringe to put a drop on the neck, under both wings, and below the vent. It takes a little time, but I prefer it to water dosing (I don't dose water with any medicines- no way to regulate how much medicine goes to which chicken). I am sure if you search around, you may find a water dosing amount for chickens. The ivermectin I bought was pour on for cattle, but I believe it's the same amount of ivermectin per mL and the sheep too.
