Well I got a new chicken and it seems like it is a little sick. She is sneezing a little and I can hear she has some congestion. I have her away from the others and I am giving Duramycin-10. She seems to be getting better. No runny nose and still eating and doing fine other than congestion. My question is can Duramycin be causing her to have a little runny stool? This is my first adult bird and I want to do everything possible for her. I got her and another from the same farm store in Austin and the others seem to be fine. She has been on the antibiotics for about two days now. I went back to where I got her and the other birds there seem to be fine. They all came from the same person and are tested. Can she just have a small cold? How is it transmitted? Can it be through the poop?
