I don't know too many people who use the metric system of kilograms in America. I certainly don't.
I think you'll find that most veterinarians, doctors, hospitals and pharmacies use it and *all* medications that we buy are labeled in milligrams (please correct me if I'm wrong).
It would depend on the type of wormer.
Yes, but I am asking about Albendazole. What is the dose in mg per kg or mg per pounds?
It would be best to contact the manufacturer.
Maybe I'll do that, should be interesting to hear what they have to say, but I think they're going to say that they can't recommend off label dosing.
Most folks brood chicks in house that I know, so they don't run the risk of getting worms until they are out on range.
Most folks? I doubt it.
I've never wormed a standard breed chicken under 3 months of age. By that time a Bantam sized dose is adequate.
So how much would you give to a 250 gram (9 ounce) bantam?
