I have another hen showing signs of being sick with a runny eye. At least I have caught the last 2 early and they are still eating and drinking. My RIR, the 1st one, is not. I took 4 to the vet for cultures to be sent to the ag vet in my region. 2 sick and 2 not. I am still not sure on what they will be looking for but I hope for a answer. It is only 3. I did add a new hen last week........No I did not keep it apart. It was one of only 6 on the place. I found out today that even if you keep them apart for the right time that if a bird is a carrier it would not matter. This is just a big crummy day!!!!!!!
