Noticed some blood in the droppings of my 5-week-olds last night and checked today and there is more. First time dealing with cocci in my flock but it's been extremely wet and muddy this spring AND my chickens have been sick with MG so I guess I shouldn't be surprised. I will hopefully be getting Corid tomorrow and plan to treat my entire chicken flock. Should I also treat my Muscovy ducks just in case?
