She has been this way for 3-4weeks all puffed up slowly walking around varely picking up food. I thought mabey she is egg bound so i soaked her washed all the yellow diarrhea off her butt but didn't seem to help. I did give her a syringe full of antibiotic just to see if it would help. That was over a week ago not much improvement but she does seem to eat a little better. The antibiotic was tetracycline in the little packet. What is corid and how much do you give a chicken? Does anyone have an idea what this could be?
