10 ml? I think that Flagyl suspension is 200 mg per 5 ml, so that's 40 mg/ml. 10 ml x 40 mg = 400 mg, which is about what I would give to a large peacock (6 kg). Small hen would get half that.For it's blackhead ... in France they use to give 10 ml of flagyl .
An adult peacock will NEVER die because of worms .... but they can die in 3 day from blackhead .... now you know what is urgent !
@Dany12, Ronidazole will also treat blackhead.
