Question about a baby tiel

[laredos_mom06]

Quarantining is essential. The other bird could have a disease Spike could get, even if it looks healthy. Here is a link about it. Good luck!

If you don't quarantine the new bird for 3-4 weeks, there's a very high chance that Spike could catch an illness from it. While I was on vacation, the caretaker of my birds introduced several new birds into the flock. He did not quarantine any of them. His lack of judgement killed off more than half my flock. Quarantine is just that important!

I think it's fine if the new bird has a smaller sized cage. S/He's only going to be living in it for a couple weeks
