I see that you can get generic Ivermectin pour-on for $17 at http://www.amazon.com/Durvet-Ivermectin-Pour-On-250ML/dp/B000HHOEIU, or $15 for "Iver On" at a Tractor Supply Co. store (See http://www.tractorsupply.com/livest...r-on-250-ml-cattle-pour-on-medication-2207056 for info).
I found a post by melissa508 on BYC: "I've always used the iver pour on for cattle for parasite control. I would use 1/2 cc on the neck & tail area for my chickens, this stuff has always worked great for mites & lice & worms."
Giving this wormer to chickens is "off-label use", meaning FDA hasn't approved that, and there are no established withdrawal times for using eggs or meat. Some people recommend waiting 30 days after treatment to eat any eggs.
Heatherberry--
From all the places I read, you've put on plenty of Ivo to take care of the worms. The ivermectin will circulate in her bloodstream, and I think worms should die within a day or 2. I don't know how quickly effects of her gapeworm infestation will subside--I imagine it will take her body a bit to absorb dead worms and repair damage. Feed her extra good nutrition while she's recovering such as vitamins and electrolytes, cooked egg yolks, unflavored yogurt, and green vegetables, in addition to her regular food.
Definitely treat all your chickens. Gapeworms are picked up from wet ground, poop, etc. All your chickens have probably picked some up.
I read it is apparently helpful to put the birds somewhere you don't usually keep chickens for a day or two after treatment. When the wormer makes worms and eggs come out of chickens' systems, you want worms to land somewhere the chickens won't usually be so they won't get picked up again. After waiting a day or two, put the chickens back in their normal living areas.
[Note: I personally am not sure if this is really helpful since it seems worms being excreted during treatment should be dead, and normal living areas will almost surely have some live worms in them even after you clean them.]
If you can, clean the floor in chickens' normal areas.
Also, sprinkling Food-grade Diamataceous Earth (available cheaply at many gardening stores) on the floor and surrounding ground will do a lot to kill off parasites that are there--I'm guessing including gapeworms.
