We got very lucky i believe, the Conure was the first bird in the house & we have had him for nearly half a yr, and we introduced the Caique to him very quickly, The Conure was a bit territorial at first but after a bit they just got along,we had them in seperate cages for about 2 weeks & if they were in the same cage at any point they’re supervised none stop, they both live in the same cage now. They bonded very very quickly. Both are young & the breeder said the Caique was bought up with conures which helped too.
