One of my bantam roosters (I have 2) started sneezing. The weather had just gotten VERY cold. He also was shaking his head. He isn't one that I can just pick up so it's been a little difficult - man those bantams can really cruise on those little legs I was able to get him after a couple of days by sneaking in the hen house early in the morning. I thought he was coughing also, but I think that the sound is actually what comes out when he tries to crow. We have had him for 2 years. He was anywhere from 1 - 3 years old then. None of our other chickens has shown any signs of being sick. Johnny has now been ill for almost a week. He is closer to being able to crow. He is sneezing less. He just still isn't feeling well and I don't know what to do. I put Eprinex pour-on on the back of his neck (I was thinking of doing this for everyone anyway - low egg prod) because I wondered and worried about gapeworm. I know it can kill a small chicken. Any ideas? I really am at a loss for something with these symptoms that isn't contagious at all! I just don't know what to do!
