I've noticed my big blue orp roo thunder is not well, he seems to be going down hill. He doesn't have nasal discharge or sneezing but his eyes look a bit swollen, his left eye has all this white goo (not foamy, its thick goo) in it, i bathed it and got it all cleaned up last night but it's back again today, he also has an injured leg from fighting with another roo and this does not look to be any better at all after 5 days in quarantine. I've treated him with tylan soluble for 3 days, finished 2 days ago. He's still eating and drinking but he doesn't seem himself at all, he is 1yr old. Does anyone have any ideas?
