Okay this is crazy. I live in the midwest and no one here (vets) know or even care about chickens enough to guide me to a medicine I can give my chickens for cocci. Seems most only do cows horses and cats dogs etc. There is blood in the droppings of my new batch of very young hens I just got. 12 of them. They are just starting to lay and look and act very healthy NOW> I do know though thr my online info they must have cocci due to blood so I want to treat them with something that will not mean a wirthdrawal period of eating their eggs IF POSSIBLE> I can get Sulmet but would prefer Amporlium product right? Any advice on what all of you do? This must happen often so what you do do?. I have 18 older layers in another coop who are and always have been disease free so this is new to me--but such a great looking group I want to cure them of this FAsT> Finding the right products online are not helpful if I can't get it at Farm and fleet . thanks for any help you can give me. Time is very improtant I understand!!
