I'm thinking I don't have gapeworm but instead one of the loathsome respiratory diseases. Long story short, brought home a new rooster from a swap about a month ago, kept him isolated and all was well. Bought from someone who was NPIP so thought I was probably safe. He just get mixed into the rest of the pack this week, too coincidental with the timing of this issue. I have NEVER lost a single bird to disease until this week. Now, I notice one of my turkey hens has a swollen face and watery eyes with sneezing. Is it time to cull everyone? I had hoped it was gapeworm that had caused my losses this week, but, not with the facial swelling on that hen. Is there any hope of it being anything but one of those diseases which they are carriers for life after getting? I picked up Tylan, but, it makes no sense to treat something that is going to spread a loathsome disease. I hatch and sell birds, well, I used to, guess not anymore. I have about 200 poults and 20 adult birds.
