Hi I’ve been worming my chickens with (from vet) panacur 100mg= 2ml per gallon water for 5 days. Vet said to do again in 30 days. Does this sound correct? I see everyone doing after 10 days. Last season same vets office different vet gave me panacur 100 was given orally .2ml per pound for 3 days in a row. And did not have to re-administer at all. I believe it was 14 day egg withdrawal. TIA
