Outside is what I mean... like do they know what bugs they shouldn't eat? During the winter and spring we get many ladybugs and I've heard they're poisonous when they're eaten. Also, I've read that chickens love to eat worms and all of that, but I've also heard that worms can carry other parasites inside them; does this affect chickens in any negative ways? What are your experiences with them eating organisms that could possible be carrying a disease? I've never had chickens in my life, I don't have any now so I'm doing as much reading and research as I can before I get some, and before I get chickens we need to fix our fence so they won't wonder the neighborhood or so other animals can't get in. We have a nice sized backyard and a hill that I think chickens would absolutely enjoy foraging on. I'm sure the area contains many types of things for them to eat, but do they know what not to eat by instinct? Any help would be appreciated! I'm new here and I look forward to learning more information on keeping and raising chickens, they seem like such wonderful animals to keep around.
