Do you have any other recommendations for meds in this case? Tylan-50 soluble didn't work, Tylan-200 injections didn't work - hens still not eating, not drinking, gurgly lungs with respiratory difficulties, sneezing, coughing - no bubbles in eyes, no runny noses, no fever that I can see - they just stand there hunched over, trying not to drown in their lungs. would penicillin help? any other meds you've tried that might work? need something injectible - at this point if i don't try something else they will die, I've already lost 9 of my sweeties... THANK YOU!!
