This morning on the ground I found a 12" long yucky worm-looking thing next to my free-range chickens, so I assume one of them pooped a worm. It was covered in greenish, poopy slime. I searched for "chicken" and "worming" and found no descriptions of this long of a worm. Does anyone know what it is? I had noticed that one chicken was having severe greenish-colored diarrhea for 2 days and was thinking I needed to treat for cocci, but maybe it was this worm. Sorry this is so gross, it makes me nauseaus just to discuss! Can I treat this chicken individually or do I have to treat the whole flock ( I think worm eggs are picked up individually). Also, is there an organic method which would not harm eggs. I would prefer not to use heavy duty chemical wormers if I can at all avoid it.
