Hello all! I just have some questions that I would like to ask the brilliant minds on this forum. I have learned so much here and than all who participate. I have several chickens who have one by one gotten those little bubbles in their eyes along with tearing and some swelling. I have been thinking it was due to a respiratory infection. Would Tylan 50 be the best thing to use? Someone at my feed store said to inject 1cc Tylan 50 and 1cc penicillin for 3 days to clear this up. Does that sound right to you all? My next question is, if giving tylan, is 3 days the recommended length of time to administer? If there isn't improvement in 3 days, can it be given longer or should another medicine be used? Thanks so much.
