my turkey 4month suddenly had one eye swollen shut with massive swelling on one side of head-no sign of injury, runny nostril and eye. It was in pain so we isolated then put down. I am worried it is respiratory or sinus infection. Will the other 6 young turkeys come down with it? What about my chickens? I don't have money to treat the whole flock. So far - 24 hours later - no one with signs yet. They all free run together in large run covered with bird netting. I could isolate the turkeys to a small covered run but then they would be in real close contact with each other. They all chickens/turkeys roost together at night. Please give advice!!
