Gapeworm treatment — Ivermectin on back for how many days?

[grnidone]

I have one hen with pretty bad Gapeworm.

I treated with spot on Ivermectin at 1 drop per 50 grams. She needed 36 drops because she was just under 1800 grams. (I weighed her with my handy dandy sourdough scale.)

Do I just give her the Ivermectin once? Or do I need to do it every day?

I read somewhere that Ivermectin doesn’t touch the adult worms, so wondering if I should give her Safe Guard Fenbendazole.

But concerned about giving too many meds at once?

@dawg53 can you advise?

Are you certain you're dealing with gapeworm? If one bird has them, most likely other birds will have them as well. A fecal float test will determine if your hen has gapeworms.
For gapeworm, it's better to use Safeguard liquid goat wormer. Dosage is 0.14ml per pound of weight given orally for 5 days straight.
