Great thread!
Here are my ideas after reading.
The comment has been made that a wild hen doesn't need to be wormed because those that lack resistance will die, and that domesticated hens are quite different in their level of immunity (therefore needing worming). That may not apply everywhere. Here in New Zealand there are several places where there are wild populations of chooks, just because people have dumped them. They thrive. People dump more alongside, and they seem to thrive too.
Also, most of us here are just a generation or two off the farm (or never left it), and the equation about cost of vet bill versus cost of animal is in our bones. A vet visit costs as much as 2-3 point of lay pullets, depending on breed of chook. So most of us would cull rather than take our chook to the vet, if things look really bad. I can't get Ivomec in small quantities except as soluble, and I'm not super confident about pouring liquid down a chook's throat. Vet also laughs when you buy it if they know its for a chook. It is really not seen as the thing to do around here. Tiny bottle with short shelf life costs half as much as a point of lay pullet. Big bottle of pour on costs as much as 3-5 point of lay pullets. So you cull, or you have all-in all-out systems, or you toy with alternative approaches that are cheaper, and don't contain the scarier herbs (like hemlock).
Love birds on the other hand have never been farm animals, so I know people who are loud and proud about worming these. They feed them oiled seed for 24 hours before worming them to aid with the expulsion of the worm load. Anyone do that with chickens?
Also, my brother being 6'5", can talk freely to his vet about worming chooks without being laughed at to his face. His vet told him to just chuck a bit of sulphur in the feed (wet mash) and it will deal with ectoparasites like mites as well as endoparasites like worms. I have never read this anywhere. Is this fair dinkum? Anyone heard of that before? (Or is this the vet equivalent of laughing at you, but specially reserved for customers with imposing physique?)
