Newer to chickens - have a 6 month old hen - her left eye is cloudy and kind of "goopie" She is holding her head oddly sort of to the side - not sure if that is because she cant see out of it so she is holding her head awkward so she can see better? Very lethargic . I gave her a shot of Penicillin G and put teramycin antibiotic eye "goo" Not getting better- any thoughts what this might be ? Thanks
