UGH! Is it possible for one chick that may have died of cocci to pass it on to the others in the brooder box and not show symptoms or die for another 5 weeks???? All the chicks I had in the brooder box were moved to the big coop about 2 weeks ago...and so far I have lost 6 out of 8 and so I isolated the other 2 left. They are ruffled up but none of them have had bloody poop. Could it still be cocci?? I dont have any anti-bs, so I have been dosing them with the electrolyte water and some plain yogurt. What else can I do?
