Please read this carefully, this chicken in question was not mine, but belonged to an older guy in one of the allotments. He culled it today. He is not on the internet but asked me if I could share this photo, if you would be able to give feedback. First of all it was a 12 week light sussex. 5 days ago he noticed that it had one of its eyes closed more than the other.Next day it was swollen and closed so he used gentamicin drops until today when he went to check on it. He described the mouth discharge as wallpaper paste. He said his crop felt empty so he hadn't been eating. It didn't have a wheezy or rattly chest. He thinks it had a peck to the eye and was possibly being kept away from food by others. He culled it because he wasn't sure what was wrong and also had not seen it eating within the last 5 days. Has anyone else seen anything like it?
