Invermectin

[ByGracechicken]

has anyone figured out the the dosage for invermectin for the chickens using the dosages that TSC has for other livestock?

What are you using?

5% Pour-On Ivermectin (topical only) is 1 mg/kg = 0.09 ml lb.
1 eyedropper drop is 0.05 ml

My silkies average 2 lb. I applied one drop on their back, behind their neck. (Could have gone with 2 but didn't want to overdose them.) I spread the feathers there and apply the drop. Repeat in 10 days. 2 weeks suggested egg withdrawal. It worked for SLM (scaly leg mites).

We went into the coop at night and did it.

Welcome To BYC

The post below has a breakdown of both Injectable and Pour On Ivermectin.

The dose is not drops. Birds should be weighed or at least have their weights guessed and the proper amount should be given. I have bolded the amount I use.

There are two types, one is injectable, the other is a pour on. The doses are different.

The max dose for 1% Ivermectin is 1 mg/kg which is 0.045 ml per pound. This can be given orally, by injection, or topically.
A five pound hen would get 0.23 ml.

The minimum effective dose for 1% Ivermectin is 0.2 mg/kg which is 0.009 ml per pound. This can be given orally, by injection, or topically.
A five pound hen would get 0.045 ml

The max dose for Pour On Ivermectin is 1 mg/kg which is 0.09 ml per pound. This is given topically only.​

A five pound hen would get 0.45 ml.

The minimum effective dose for Pour On Ivermectin is 0.5 mg/kg, which is 0.045 ml per pound. This is given topically only.
A five pound hen would get 0.23 ml

DO NOT USE this on your dogs unless you are working with a vet!​
