Peahens dying!

[calikid]

I lost peahen today and another is sick! Separated from the flock already. I recently acquired a pair of pheasants. The female ended up sick with swollen shut eyes and enlarged upper back part of mouth. White in color. ended up dying. I kept them away from my other birds but now my peahens are sick. They're not eating. The back of their mouths are swollen and white in color as well but no shut eyes! Please help!
