I just finished a quarantine period... i know it is a huge pain. As for the shirt thing... I did the same thing, only if they were crawling around on me, and LOTS of hand washing. Generally you quarantine for at least 30 days. However, I have had the babies for about 3 weeks. Yesterday they went to a vet check, and the vet cleared them. he said it would be okay to introduce them to Bubba, so I did

, with his blessing. If you have been in contact with the woman, maybe ask who her vet was, if you can get a copy of their records, when they were checked last, etc.

, female cockatiel).
