I have a chicken i just got from the auction that i put on tylan 50 injections. She had a runny nose and was sneezing, coughing, and shaking her head a lot. She has been on injections for about 5 days and her symptoms seem better but she has diarrhea and some of it is bright green and she doesn't have much of an appetite. I have been giving her shots of b vitamins to stimulate her appetite. The green in her poop looks like mini green intestines. What causes this? The only thing she has been eating is dumor 20% feed. I don't like dumor but they were out of flock raiser at TSC. I have pics but i don't know how to post them. If you can tell me how i will post pics.
