Flubendazole 1% Individual Dosage?

[Adey65]

Two of my hens recently had a heavy, and somewhat late moult. One of them has been unwell for a week now with diareaha, although up until yesterday she was eating enthusiasticaly, more so than normal, which makes me think she has worms. As they are all due to be wormed anyway at the end if this month, I was wondering what the dosage is for an individual chicken using Flubendazole 1%? I ask because the bird in question is not eating enough now so it's very unlikely she'd get enough of the medication if mixed in her food. Instead I intend to add the correct dosage to an empty capsule and administer orally. I already gave her 0.3g today(which I think is the correct amount?) mixed with some coconut oil. I think the capsules will make it easier I'm just waiting for them to arrive later today. I just want to know if the 0.3 g is correct. Sorry for the long post.
