I have a 2-3 year old Polish Roo that started showing symptoms of a swollen puff eye(the only symptom). I gave him some Tylan 50 and it cleared up. He now has become lethargic, almost sleepy and has loss of balance and turns his head to the side. I pulled a hard plug out of his ear. He sleeps all day and I can pick him up, he will stand with eyes open for a few seconds then falls back to sleep. I gave him liquid Baytril for 3 days with no improvement. I started him today on 1/2 cc penicillin and gave him a small amount(1/8 cc) of liquid steriods incase their was swelling going on. I have been tube feeding him baby bird feeding formula & also some poultry cell mixed in. No mites or lice......no snotty nose..... I don't know what is wrong with him... I keep him in a chicken barn, on wire up off the ground. He gets a local mills chicken layer as with all my chickens..... any clues?
