I am really having a problem with round worms. My guineas started dying all of a sudden. We had 20 but now we have 9. This is a MAJOR problem. We disected one dead guinea and found worms in their intestines. We did research and found out that they were called roundworms. If my guineas have it, im sure my chickens do too. I put garlic in the chickens water, the guineas water and in the backyard. I heard garlic water helped, im just not sure id thats enough. If there is ANY cure that ANYBODY knows. PLEASE help. This is a serious problem, and I don't want my chickens to die too. Does anybody else know a cure?
