please do not introduce them as of yet.. quarantine them for 30 days at least...

birds can hide illnesses sooo well... that when you know they are sick they are practically at their last and it can pass from bird to bird... so for Bobbie´s sake.. quarantine them in separate rooms...as far as possible you can... then you can start introducing them by placing them side by side...

this time will help her also to get adjusted to the noises at your house and more importantly to you, so use this time to bond with her.....
