I got a second tiel last night and spent the night and morning with her before going to school. When I got home, she wasn't in the living room anymore but in my room. With Oz. I guess I didn't stress the importance of quarantine enough when I explained it to the family before I left and it seems they thought a few hours together would cause the birds no harm (still in separate cages of course). So, they spent quite a bit of time locked in a room together so is it safe to assume that any illness she might have has already been transferred? Should I separate them again or is there just no point anymore? The cages were pretty close...
