My understanding is that its very good for chickens to free range,, dig, scratch, eat bugs, worms, etc. But when someone asks for advice on parasite problems for instance gapeworm, tapeworm, etc. they are told the chicken gets it from eating bugs and worms . The bugs are host carriers of parasitic eggs. My conclusion is that chickens shouldn't be allowed to eat earthworms especially, or am I just too mind boggled by differing opinions? Help. I feel a case of the vapors coming on and will retire to the swooning couch.
