just my opinion..but knowing for sure is important..
so, I'd do the swab and get a test done.
could the blood you're seeing be from pecking and fighting from being cooped up?
are the birds throwing mucus, or bloody mucus?
ILT is the only thing I can think of that cause that symptom..
tho it's slightly possible they could have sinus infection and respiratory illness..
Tylan 50 or Tylan 200 injectable would treat that..
best to know for sure.
