Quote:
Did you know chickens get worms from eating earthworms, etc? ....
This is a quote from a Florida Extension Service article.
The chickens pick up the parasite eggs directly by ingesting contaminated feed, water, or litter or by eating snails, earthworms, or other insects (intermediate hosts) which can carry the eggs. Further down it mentions earthworms and grasshoppers as intermediate hosts for roundworms.
Just for the record, here's a link to the article.

Unless you keep your chickens in solitary confinement, away from earthworms, insects, and wild birds, there is a great chance they have worms. The contaminated feed, water, and litter means that it has bird droppings in it, like when an infected bird perchs above a feeder or a wild bird leaves a deposit in the run.
Some worm prevention methods:
Keeping the grounds dry and clean. Use pine shavings (not chips) instead of hay, put down sand instead of letting them be on bare soil. These methods dry out the ground and worm eggs and bacteria have a harder time existing in those conditions. They keep the birds' area more hygienic and thus more clean smelling. It's WAY easier to clean, too!
For treats like scratch, use in the bedding instead of the ground. They'll fluff up and aerate the bedding for you, have less access to droppings and shed parasite eggs, and will dry the bedding as well.
Kathy,
There is something so basic to me about my chickens eating these things that I can't bring myself to keep it out of their diet. I LOVE my "yard art" wandering around eating all the little nasty creatures I can't see but they love. I use DE in their feed pretty regularly and I also use wood chips in their coop as well as hay in the yard (for when I don't just let them range.) I may try your idea of the sand though. That might be a better choice for the run instead of hay. Have you used the sand before and what was your success? In the article you mentioned, I had to laugh at the idea of keeping birds away from my "free range" flock. Not really realistic but would work if you keep your girls confined I guess.
