My new chickens are actually part of a larger effort to make better use of our food and paper waste and to produce more of our own food. It actually began with a wormbin that I have maintained for about a year now.
My plan all along has been to feed excess worms to my chickens.
Raising worms is easy and rewarding, and in my experience the more expensive and fancy the wormbin, the worse. Your mileage may vary, but I'm really happy to see paper waste, food contaminated paper waste, dryer lint, used paper towels, etc. be turned into incredibly rich soil and tons of worms.
I'm looking forward to scooping out a load of worms and compost from the bin and dropping it on the ground for the chickens to distribute over my lawn.
A fascinating article on this topic that expresses a larger version of my ultimate goal is here:

The one caveat that I will offer is that as I understand it, heavy metals can build up in a worm, and it stands to reason if your chicken eats a worm full of heavy metals, the chicken will be full of heavy metals. For this reason, it pays to be conservative about what goes into the bin. From Appelhof's book Worms Eat My Garbage, I gather that keeping colored inks and colored papers out of the wormbin is one way to reduce heavy metal content.
Because of our general environmental toxicity, some contamination is going to be unavoidable. And worm bins are very dirty. They attract all manner of creepy crawly - they are not the tidy things shown in magazines for sure.
In other news, composting worms can defend against and help to eliminate e. coli from your microsystem:

There are other studies that show that compost worms can eat infected material and reduce and eliminate harmful bacteria from it - in effect sanitizing the material.
As far as earthworms giving chickens worms, I did find some information here:
http://palekarzerobudgetnaturalfarming.com/organic.html "Augustinc & Lund 1974 and Jakovlijevic 1975 have shown that, the parasitic nematode Ascaris Suum in Pig and Ascaridia Galli in chickens are transmitted by these worms."
Wikipedia does indeed say that it is suspected that Ascardia Galli is carried by earthworms. I was not able to find the Augustinc & Lund study, but the author of this page has misinterpreted the Jakovlijevic study. First, it has to do with a different type of worm and pigs, not e. foetida and chickens. The abstract for that indicates that the worm studied was not a carrier:
http://www.bioone.org/doi/abs/10.1654/1525-2647(2002)069[0206:TELTAA]2.0.CO;2?journalCode=copa
"No intermediate or paratenic host role for L. terrestris in the As. suum life cycle was demonstrated. "
So for those of you who are chicken-experienced - it seems like the threat of eating earthworms is parasitic worms? Does worming or DE adversely effect chickens?
