Hi, I have 2 birds (budgies) and they have been really healthy. However, over the past few weeks my female bird has been wheezing and sneezing quite a bit. It's almost like she is having a tough time breathing. Oddly enough, she is still eating normally, hasn't lost weight and still has quite a bit of energy unless she fly's around the house for too long...then she is out of breath. Can someone please let me know what I should do since I hate seeing her like this. Also, does anyone know what may be wrong with her and if so what treatment I should give her? :'(
