I have a 24 year old yellow naped amazon and a sun conure. Today I was asked to babysit a Pineapple green cheeked conure for a few days. My amazon loves other birds and I believe will have no problem with the new bird. My sun however is very unsure around new birds and I wish for this to be a good weekend for both my birds and the visiting bird. Any suggestions on what I can do to help everybody get along?
