i have a six month old bourbon red that is acting a bit sick. kinda slugish, laying around alot. eating and drinking. he does have some green poo hanging from is bottom feathers.he is not blocked up that i can tell. i did deworm with wazine 17 12 days ago. everyone has seemed fine until now. chickens, guineas, and turkeys all free range where ever they want to go, outside the two strand hot wire. i have lost two hens already and i dont want to loose anymore. this one i hatched and raised, the others that died i bought a couple months ago. anyone with any ideas.
