Is there harm in treating for cocci?? They do not have blood in their droppings, but at this point I am desperate. It is runny in the chickens that have died. My buffs are fine, but my older birds I am losing at a rate of one per month or so. Go to my post that is a bit lower in this part of the forum that says Another hen dying, HELP! And you can read all that I have to say about what is happening in my chicken population. Suggestions are so welcome.
