Have you had any confirmed cases of gapeworms? If not, I think you might be dealing with respiratory infections. I strongly suggest that you start getting routine fecals done and treat accordingly. If you are losing birds, it would be best to have a necropsy done and find out exactly what you're up against.

Exactly... and I had gapes mimic respiratory...
