Side effects for living in a house with a bunch of finches?

It is normal if you keep the cage clean and freed the birds. If you do this, but just try to keep like 2 or 5. What you may be feeling is the poop, or the dandruff from the birds from when they scratch their heads (i think they do that, i seen parakeets do it). Breathing in the air with the poop and urine from the birds can make u sick i think. I hope i helped :) and i hope u feel better and ur mom, from all the headaches and such.
