I've tried my hardest to find that dosage chart but finding things on here is a chore and a half lol! But here's how I dose my girls and the rooster. Half a pea sized dollop each bird, two weeks later I repeat the dose to get any worms that have hatched since the first dosage. I do this twice a year, once at the beginning of spring and once right before winter. My flock free ranges so keeping on a schedule helps keep the parasites at bay before they can cause bigger issues. 

Thanks for the good info everyone. Now to see if I can find it! Chickassan, you said you do a half of a pea size dollop for each bird- how often? I like the word “forgiving” quite a bit- along with Chickencountryuk’s comment that it’s used to treat people for parasites as well. That’s at least a little comfort for somone who’s so paranoid about chemicals/drugs. I thank you, and so do “the girls”! Let’s hope this plumps them up a bit- because it’s the last resort. I guess that being the case, if they don’t plump up, then I can relax in knowing they’re just naturally a flock of skinny biotches!
