I just bought a barred rock rooster Friday evening, he is supposed to be around ten months old. Didn't notice anything Friday evening but I noticed one of its eyes was closed the next morning and now it is covered whitish / yellow, he stands around a lot of the time fluffed up and makes some occasional noise, maybe a cough or sneeze. I put him with the hens yesterday morning before I realized he wasn't well, usually keep separated longer but this time I didn't. I have taken him back out this evening and have him isolated. He seems to be eating and drinking, moves around pretty good if you get around him or another chicken pecks at him. Below are a couple of photos of his eye. Any suggestions on what should be done? Should I be concerned with the hens he was with since yesterday? Thanks for your help.
